“A REVIEW STUDY ON STEEL STRUCTURE SUBJECTED TO BLAST LOADING”IRJET Journal
This document summarizes a study on the progressive collapse of steel structures subjected to blast loading. The study uses numerical modeling software to analyze the behavior of steel buildings when exposed to blast events from vehicle bombs and package bombs. Different structural systems are examined, including models with and without exterior walls. The numerical models are validated by comparing results to published examples of steel components under blast loading. Key findings include that exterior blast events primarily damage exterior structural members, and that enhancing the shear capacity and ductility of columns can help prevent collapse. Distributed damage to exterior columns is found to increase vulnerability to progressive collapse compared to localized column damage.

Behavior of RCC Structural Members for Blast Analysis: A ReviewIJERA Editor
In today’s scenario threat of enemies and terrorist attack is increasing. Therefore consideration of blast load in analysis and design is essential. A bomb explosion within or nearby outside the building can cause catastrophic failure of building. Blast loads have, in the recent past, become important service loads for certain categories of structure. An important task in blast resistance design is to make a realistic prediction of blast pressure. The distance of explosion from the structure is an important datum, governing the magnitude and duration of blast loads. In the present study, the RCC frame was analyzed by using conventional code for gravity loads using moment resisting frame. The blast load was calculated using UFC-340-02 (2008) or IS 4991-1968 for 500 kg and 100 Kg TNT at standoff distance of 10m and 30m from face of column at first floor level. The triangular impulse was applied as nodal time history at all front face joints. The analysis was performed using Computer aided software.

This document discusses a numerical study that investigated the effects of different reinforcement schemes and column shapes on the blast resistance of reinforced concrete columns. The study used finite element analysis to model RC columns with varying transverse reinforcement spacing, axial load levels, column shapes, and longitudinal reinforcement arrangements. The results showed that transverse reinforcement spacing, axial loading, and column shape significantly affected the behavior of RC columns under blast loading, with more closely spaced transverse reinforcement and circular columns displaying higher blast resistance. The longitudinal reinforcement arrangement also influenced column response to blast loading at low scaled distances. The study aims to improve understanding of RC column behavior under blast loading to inform more blast-resistant design.
Seismic Performance of RC Frame Building with Different Position of Shear Wallijtsrd
An earthquake force is a very strange force and behaves quite differently than Gravity and Wind loads, striking the weakest spot in the whole three dimensional structure. It’s not earthquake that kills, in fact ignorance in design and poor quality construction results in many weaknesses in the structure that cause serious damage to life and property. Masonry Infill are frequently used to fill the gap between the vertical and horizontal resisting elements of the building frames with the assumption that these in fills will not take part in resisting any kind of load either axial or lateral. Hence, its significance in the analysis is generally neglected by the designer. In fact, infill wall and shear wall considerably enhance the rigidity and strength of the frame structure. Various researches suggest that the bare frame has comparatively lesser stiffness and strength than the infill frame and frame with shear wall, therefore their ignorance cause failure of many multistorey buildings when subjected to seismic loads. In the present study, the finite element analysis of RC frame models viz. a bare frame a frame with shear wall considering infill a bare frame with shear wall has been carried out and the number of storeys vary as G 3, G 5, G 7 and G 9. Linear analysis of all RC frame structures has been performed as per IS 1893 Part 1 2002 and IS 456 2000. In this study only in plane stiffness of masonry wall has been considered and infill panels modelled as equivalent diagonal strut elements. The behaviour of buildings subjected to Gravity and Seismic loads with the help of Response Spectrum Analysis using FEM based software and the effect on Time Period, Mass Participation factor, and Storey Drift has been observed. Strength and Rigidity of RC bare frame structures is found increasing after the inclusion of infill panels and shear wall.

This document discusses a study that analyzed the response of a rectangular reinforced concrete structure with and without shear walls under blast loads. Finite element models of a building frame with and without shear walls were created in SAP2000 software and subjected to blast loads. Parameters like displacement, member forces, and story drift were compared between the bare frame model and frame-shear wall model. The results showed that integrating shear walls improved the structure's performance under blast loads by reducing displacements and member forces.
This document reviews research on the progressive collapse of steel high-rise buildings exposed to fire. It discusses key influencing factors on whether and when a structure may collapse, and what type of collapse may occur. These factors include load ratios, beam and column strength, slab performance, connection strength, fire scenarios, bracing systems, and fire protection. Higher load ratios, strong beams, multi-compartment fires, and lack of fire protection make global downward collapse more likely. Bracing systems and fire protection can effectively prevent progressive collapse. Further research using 3D models is needed to accurately predict collapse under various fire scenarios.
This presentation summarizes Sarang Wakharkar's research on designing impact resistant overhead protection structures and blast proof chambers. The research investigated passive protective measures for existing facilities vulnerable to enemy munitions. A modular structural system was designed using commercially available materials like tubing and scaffolding. Structural analysis software modeled 9 configurations to understand how dimensions relate to load capacity. The design was analyzed under conditions in Parwan Province, Afghanistan. Preliminary findings showed commercially available materials can quickly install overhead protection in hostile areas. The presentation outlines objectives, methodology, literature review, and plans to analyze and design sample structures to resist blast loads at different distances.
Comparative Study of Response of Structures Subjected To Blast and Earthquake...IJERA Editor
The increase in the number of terrorist attacks especially in the last few years has shown that the effect of blast
load on building is a serious challenge that should be taken in to consideration for designing of structures. This
type of loading damages the structures, externally as well as internally. Hence the blast load should be
considered with same importance as earthquake load. The present study includes the comparative performance
of G+3 storey building subjected to blast and earthquake loading using ETABS. For four storey building using
different input parameters like charge explosive, stand-off distance and layout of building the blast pressure are
conducted and linear time history analysis is carried out. Comparative study for blast and earthquake loading is
carried out for different parameters like maximum storey displacement, storey drift and quantity of materials.
Safe charge explosive and safe stand-off distance are obtained for the RCC structure with the sections of
structural elements same as per the requirement for earthquake resistance. Displacement is higher for the blast
loading as compared to earthquake loading and very high for the storey at which blast load is applied. Quantity
of concrete is 40 percentages higher for blast resistant building than the earthquake resistant building.
Progressive collapse analysis in rc structure due to 150513181706pradip patel
Now in the recent time of terrorism, structural engineers require new consideration of terrorist attack in the design standards. Modern day structures pose a unique challenge to designers due to increased terrorist activities. Bomb blasts, vehicular attacks, Arson, Armed based attack all may result into a partial or total collapse of buildings. The work undertaken is an attempt to recognize the behaviour of RC structure under series blast loading. A model of G+4 RC structures has been considered as a progressive collapse analysis. The RC building with effect of series blast loading is analysed by using linear static and dynamic analysis. The present study work will carry out the effective study of different parameters like; different types of explosive charges (5T-5T, 7.5T-7.5T, 10T-10T TNT) at 10 mt. stand-off distance, failure of structure element at storey level and the structure is checked for progressive collapse by using commonly available, widely used software SAP 2000 will utilize for analysis

This document presents a study on the performance of high-rise buildings with bracing and diagrid structures under lateral loads. It analyzes a 30-story building model with different structural configurations - a regular frame, diagrid system, and bracing system - using the ETABS software. The study finds that the diagrid structure performs best in terms of minimizing storey displacement, drift, and increasing frequency compared to the other models. It concludes that the diagrid structure is the stiffest and most effective at resisting lateral loads like earthquakes. Bracing systems are also better than bare frames at increasing stability, but diagrid structures provide the best performance overall.

This document analyzes the dynamic response and failure of elevated INTZE storage tanks under external blast loading. It describes modeling INTZE tanks in SAP2000 software and applying blast loads to study displacements, reactions, stresses over time. Frame and shaft footed tanks of varying heights were analyzed both empty and full. Results show shaft footed tanks resist blast loads better due to more mass concrete. Displacements increase with frame tank height but decrease for shaft tanks. Stresses also increase with height for both, but are lower for shaft tanks. Failure analysis indicates pillars and connections initially fail from stress concentrations. The conclusion is shaft footed tanks with maximum height best resist blast loads.

Comparative Study on Masonry Infill, Friction Dampers and Bare Frame Structur...IRJET Journal
The document compares the seismic response of a 10-story building modeled with three different configurations: a bare frame, a frame with masonry infill walls modeled as equivalent diagonal struts, and a frame with friction dampers. Non-linear time history analysis was performed using the EL Centro earthquake record. The addition of masonry infills increased the lateral stiffness and decreased displacements and column moments but also increased base shear and accelerations. The use of friction dampers effectively dissipated energy and reduced the structural response compared to the bare frame, without increasing other demands. Analysis results for story acceleration, displacement, column moment, and base shear are presented for each model.

This document discusses analyzing the response of a reinforced concrete building to blast loads. The building was modeled in Inventor and analyzed in Altair and Staad Pro. Transient structural analysis was used to simulate the effects of uniform blast pressure loads at different standoff distances. The objectives were to study deformation of the structure under positive and negative blast phases and compare effects of blast pressure at 5m and 6m standoffs. A 3-story commercial building was modeled and analyzed, with blast assumed from the front corner at 5m and 6m distances.

This study analyzed the effect of horizontal energy dissipation beams on the seismic and progressive collapse resistance of dual braced moment frames. Nonlinear dynamic and static analyses were performed on frames with and without energy dissipation beams. The results showed that including energy dissipation beams reduced frame displacement by 3% and base shear by 23% under seismic loading. In progressive collapse analysis, frames with energy dissipation beams exhibited improved resistance when columns were removed, increasing load capacity by up to 15.48% compared to frames without beams. The energy dissipation beams improved the overall seismic and progressive collapse performance of the dual braced moment frames.

This document discusses two issues related to assessing buildings subjected to explosions: 1) Evaluating the robustness of steel frame structures through "robustness curves" showing residual strength under different damage levels, applied to a 20-story steel building. 2) Precisely evaluating blast pressures on structures using Computational Fluid Dynamics, focusing on how room congestion, wall failures, and ignition points influence gas explosion development. The analyses provide robustness curves to assess risk and show pressure variations due to analysis parameters are significant.

This paper addresses two main issues relevant to the structural assessment of buildings subjected
to explosions. The first issue regards the robustness evaluation of steel frame structures: a procedure is
provided for computing “robustness curves” and it is applied to a 20-storey steel frame building, describing
the residual strength of the (blast) damaged structure under different local damage levels. The second issue
regards the precise evaluation of blast pressures acting on structural elements using Computational Fluid
Dynamic (CFD) techniques. This last aspect is treated with particular reference to gas explosions, focusing
on some critical parameters (room congestion, failure of non-structural walls and ignition point location)
which influence the development of the explosion. From the analyses, it can be deduced that, at least for the
examined cases, the obtained robustness curves provide a suitable tool that can be used for risk management
and assessment purposes. Moreover, the variation of relevant CFD analysis outcomes (e.g., pressure) due to
the variation of the analysis parameters is found to be significant.
A Review On Behavior Of Tall Structure Under Blast LoadingIRJET Journal
This document summarizes research on modeling the behavior of tall buildings under blast loading. It describes how an 11-story building model was analyzed using ETABS software at different charge weights (100kg and 200kg) and standoff distances (20m and 40m). The response of the building in terms of story displacement and drift was examined. Four additional structural models using different systems were also analyzed and compared to identify the most blast resistant system. Previous research studies on blast loading and structural behavior are summarized, showing increased charge weight and decreased standoff distance significantly impact structures. Graphs demonstrate increased story drift with higher charge weights but decreased drift with greater standoff distances. Irregular buildings are most vulnerable with the highest inter-story drift values

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

The work undertaken is an attempt to recognize the behaviour of RC structure under series blast loading. A model of G+4 RC structures has been considered as a progressive collapse analysis. The RC building with effect of series blast loading is analysed by using linear static and dynamic analysis. The present study work will carry out the effective study of different parameters like; different types of explosive charges (5T-5T, 7.5T-7.5T, 10T-10T TNT) at 10 mt. stand-off distance, failure of structure element at storey level and the structure is checked for progressive collapse by using commonly available, widely used software SAP 2000 will utilize for analysis
IRJET- Performance Study of High Rise Building with Bracing and Diagrid Struc...IRJET Journal
This document presents a study on the performance of high-rise buildings with bracing and diagrid structures under lateral loads. It analyzes a 30-story building model with different structural configurations - a regular frame, diagrid system, and bracing system - using the ETABS software. The study finds that the diagrid structure performs best in terms of minimizing storey displacement, drift, and increasing frequency compared to the other models. It concludes that the diagrid structure is the stiffest and most effective at resisting lateral loads like earthquakes. Bracing systems are also better than bare frames at increasing stability, but diagrid structures provide the best performance overall.

This document analyzes the dynamic response and failure of elevated INTZE storage tanks under external blast loading. It describes modeling INTZE tanks in SAP2000 software and applying blast loads to study displacements, reactions, stresses over time. Frame and shaft footed tanks of varying heights were analyzed both empty and full. Results show shaft footed tanks resist blast loads better due to more mass concrete. Displacements increase with frame tank height but decrease for shaft tanks. Stresses also increase with height for both, but are lower for shaft tanks. Failure analysis indicates pillars and connections initially fail from stress concentrations. The conclusion is shaft footed tanks with maximum height best resist blast loads.

Comparative Study on Masonry Infill, Friction Dampers and Bare Frame Structur...IRJET Journal
The document compares the seismic response of a 10-story building modeled with three different configurations: a bare frame, a frame with masonry infill walls modeled as equivalent diagonal struts, and a frame with friction dampers. Non-linear time history analysis was performed using the EL Centro earthquake record. The addition of masonry infills increased the lateral stiffness and decreased displacements and column moments but also increased base shear and accelerations. The use of friction dampers effectively dissipated energy and reduced the structural response compared to the bare frame, without increasing other demands. Analysis results for story acceleration, displacement, column moment, and base shear are presented for each model.

This study analyzed the effect of horizontal energy dissipation beams on the seismic and progressive collapse resistance of dual braced moment frames. Nonlinear dynamic and static analyses were performed on frames with and without energy dissipation beams. The results showed that including energy dissipation beams reduced frame displacement by 3% and base shear by 23% under seismic loading. In progressive collapse analysis, frames with energy dissipation beams exhibited improved resistance when columns were removed, increasing load capacity by up to 15.48% compared to frames without beams. The energy dissipation beams improved the overall seismic and progressive collapse performance of the dual braced moment frames.

Numerical analyses for the structural assessment of steel buildings under exp...Franco Bontempi
This paper addresses two main issues relevant to the structural assessment of buildings subjected
to explosions. The first issue regards the robustness evaluation of steel frame structures: a procedure is
provided for computing “robustness curves” and it is applied to a 20-storey steel frame building, describing
the residual strength of the (blast) damaged structure under different local damage levels. The second issue
regards the precise evaluation of blast pressures acting on structural elements using Computational Fluid
Dynamic (CFD) techniques. This last aspect is treated with particular reference to gas explosions, focusing
on some critical parameters (room congestion, failure of non-structural walls and ignition point location)
which influence the development of the explosion. From the analyses, it can be deduced that, at least for the
examined cases, the obtained robustness curves provide a suitable tool that can be used for risk management
and assessment purposes. Moreover, the variation of relevant CFD analysis outcomes (e.g., pressure) due to
the variation of the analysis parameters is found to be significant.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
