This document analyzes the effect of using lead rubber bearing (LRB) isolators on structures of varying heights when subjected to seismic activity. Non-linear time history analyses were conducted on 4, 10, 15, and 20-story rectangular reinforced concrete structures both with and without LRB isolators. The results showed that using LRB isolators significantly reduced story rotation, acceleration, displacement, and drift across all building heights compared to fixed-base structures. Additionally, LRB isolators increased the natural period of the structures, which decreased the lateral forces experienced. In conclusion, seismic isolation through the use of LRB isolators improved the performance of structures and was more effective at mitigating earthquake effects in taller buildings.

The recent history of earthquakes have indicated that if the structures are not properly designed and constructed with required quality may cause great damage to structures. This fact has resulted in to ensure safety against earthquake forces of tall structures hence, there is need to determine seismic responses of such building for designing earthquake resistant structures by carrying seismic analysis of structure. In the present work dynamic analysis of G+12 RC multi-storied framed building considering for Koyna and Bhuj earthquake is carried out by response spectrum analysis and time history analysis and responses of such building are comparatively studied with the help of SAP2000 software. Two time histories (i.e. koyna and Bhuj) have been used to develop different acceptable criteria (base shear, storey displacement, storey drift). From the results it is recommended that time history analysis should be performed as it predicts the structural response more accurately than the response spectrum analysis. Pushover Analysis is also performed for the same building and from results it is found that building is seismically safe.

Seismic pounding effects on adjacent Tall buildings – A ReviewIRJET Journal
This document reviews research on seismic pounding between adjacent tall buildings. Seismic pounding occurs when buildings collide during earthquakes due to insufficient separation gaps. It can cause severe damage through concentrated local impacts, increased floor accelerations, and failure of structural elements. Past studies show that differences in building height, mass, and period most affect pounding. Mitigation strategies include increasing separation gaps, adding stiffening elements like shear walls, and using damping devices. However, mid-column pounding and optimal damper selection and placement require more research to effectively mitigate seismic pounding risks.

This document discusses evaluating the seismic performance of Mivan structural systems compared to conventional structural systems through pushover analysis. Mivan structures use load-bearing shear walls instead of columns and beams, providing a faster construction method. Both structural systems were modeled for 3, 6, and 9 story buildings with identical plans, elevations, and soil-structure interaction. Pushover analysis was conducted to determine the base shear-displacement response and failure modes of each system. The results show that Mivan structures performed better seismically than conventional structures under both gravity and seismic loads.

Effect of fines on liquefaction using shake table testeSAT Journals
calamities resulting into considerable damages. One of the most detrimental
effects caused due to earthquake is liquefaction. This paper deals with experimental investigation of effects of fines content on
liquefaction behavior using shake table test. A test program consisted of total 19 tests conducted on saturated cohesionless sand
with varying amount of non-plastic silt. The behavior of such silty sand in the relative density range 30 to 60% has been studied
by subjecting the specimens to a specific acceleration of 0.54g. Effect of silt content and the relative density on generation of pore
pressure and thereby initiation of liquefaction has been studied. The results obtained from the present study showed that cyclic
stress ratio (CSR) values decrease with the increase in fines content for lower relative densities. Delay in development of pore
pressure is observed with the increasing fines content. This indicates that higher silt contents at higher densities offer better
resistance to liquefaction. Further, for lower densities and lesser silt contents liquefaction occurred at pore pressure ratio even
less than one. The trend observed for CSR and relative density is similar when compared with triaxial test reported in literature.
The points where liquefaction has occurred in the field, when checked in the present study, they lie in ‘YES’ zone of liquefaction.

This document studies the influence of core wall positions on structures with a step back configuration. A steel building model with step back configuration is developed in ETABS software. Different core wall layouts in C and U shapes are modeled at various positions within the building. The building is analyzed using time history analysis for a high seismic zone with medium soil. Results for various core wall positions are compared in terms of displacements, torsion, and other seismic response parameters. It is found that positioning the core walls in a C shape at the center of the building (layout sw7c) results in the lowest displacements and torsion compared to other positions studied, making it the optimal core wall arrangement for the step back building model.

This document analyzes the use of a tuned liquid damper (TLD) in a G+6 building with a top rectangular water tank in Ambikapur, Chhattisgarh, India to control vibrations. The building is analyzed under various dynamic loads. A TLD uses liquid sloshing to dampen structural oscillations. Analysis shows the TLD can effectively reduce responses to half of original values. Properly designed TLDs with optimal tuning ratio, depth ratio, and mass ratio are effective at reducing structural response to earthquakes and winds. The top water tank in this building acts as a TLD. Nonlinear models are used to analyze the liquid-structure interaction.

accommodate parking facilities for the vehicles of the occupants of the building. As we know that the soft storey in a building
structure causes stiffness irregularity in a structure, due to this the structure undergoes unequal storey drifts, formation of the
plastic hinges and then finally resulting into the collapse of the structure.This research work purely interacts with the effect of the
soft storeys in the analysis of RC framed structures as entitled above, and in this work the soft storeys positions has been provided
at different levels as shown in the analytical modelling. All the models are analyzed by using the ETABS software. The seismic

This document reviews research on the effect of soil-structure interaction (SSI) on the dynamic behavior of structures. SSI considers how soil flexibility affects a structure's response to seismic loading, which is important for high-rise buildings or those on soft soil. The document outlines the history and development of SSI analysis, how SSI is modeled using finite element software, and its effects observed in past earthquakes. It discusses that SSI can both increase structural flexibility and displacements, as well as have adverse effects by increasing demands on ductility depending on site conditions. More research is still needed to better incorporate SSI considerations into seismic design codes.

Mivan structures use load-bearing shear walls instead of columns and beams, providing a faster construction method. Both structural systems were modeled for 3, 6, and 9 story buildings with identical plans, elevations, and soil-structure interaction. Pushover analysis was conducted to determine the base shear-displacement response and failure modes of each system. The results show that Mivan structures performed better seismically than conventional structures under both gravity and seismic loads.

Seismic Analysis of Irregular Building Frames with Soil Structure Interactionijtsrd
Seismic response of structure is extremely complex because of the non linear behavior soil during earthquakes. Seismic design of structures is generally carried out assuming fixed base ignoring the flexibility of soil. The main objective of the study is to investigate the significance of effect of soil structure interaction on building with mass irregularity. The dynamic contact approach was utilized to simulate pounding between the adjacent buildings. Nonlinear finite element analysis was performed for two adjacent multi story structures with four different configuration representing cases that can exist in reality. The seismic response of the studied cases generally emphasized that ignoring the soil flexibility and or the contribution of the infill panels may significantly alter the response of adjacent structures. Response spectrum analysis has been carried out and the parameters like time period, base shear, roof top displacement and storey drift of the building frames resting over foundation and soil media has been studied.

Effect of fines on liquefaction using shake table testeSAT Journals
calamities resulting into considerable damages. One of the most detrimental
effects caused due to earthquake is liquefaction. This paper deals with experimental investigation of effects of fines content on
liquefaction behavior using shake table test. A test program consisted of total 19 tests conducted on saturated cohesionless sand
with varying amount of non-plastic silt. The behavior of such silty sand in the relative density range 30 to 60% has been studied
by subjecting the specimens to a specific acceleration of 0.54g. Effect of silt content and the relative density on generation of pore
pressure and thereby initiation of liquefaction has been studied. The results obtained from the present study showed that cyclic
stress ratio (CSR) values decrease with the increase in fines content for lower relative densities. Delay in development of pore
pressure is observed with the increasing fines content. This indicates that higher silt contents at higher densities offer better
resistance to liquefaction. Further, for lower densities and lesser silt contents liquefaction occurred at pore pressure ratio even
less than one. The trend observed for CSR and relative density is similar when compared with triaxial test reported in literature.
The points where liquefaction has occurred in the field, when checked in the present study, they lie in ‘YES’ zone of liquefaction.

The top water tank in this building acts as a TLD. Nonlinear models are used to analyze the liquid-structure interaction.
Effect of soft storeys in earthquake resistant analysis of rc framed structureseSAT Journals
storey in which the stiffness is less than 70% of the storey above or less
than 80% of the combined stiffnesses of the three storeys above. It is the general practice in the multistoreyed buildings to
accommodate parking facilities for the vehicles of the occupants of the building. As we know that the soft storey in a building
structure causes stiffness irregularity in a structure, due to this the structure undergoes unequal storey drifts, formation of the
plastic hinges and then finally resulting into the collapse of the structure.This research work purely interacts with the effect of the
soft storeys in the analysis of RC framed structures as entitled above, and in this work the soft storeys positions has been provided
at different levels as shown in the analytical modelling. All the models are analyzed by using the ETABS software. The seismic
analysis performed consists of the Equivalent static analysis (ESA), response spectrum analysis (RSA), and the push over analysis
(PA). The seismic base shear forces, storey drifts, and the displacements has been compared with the three analysis methods as
listed above. With the aid of the push over analysis the values of the ductility and the response reduction factor have been
obtained. Apart from these, the performance point parameters such as spectral acceleration(Sa) , spectral displacement (Sd),

More research is still needed to better incorporate SSI considerations into seismic design codes.
VARIATION OF SEISMIC RESPONSE OF MID-RISE RC BUILDINGS DUE TO SOIL STRUCTURE ...IAEME Publication
The seismic design of RC buildings requires determining the expected base shear, lateral drift at each story level and internal forces of the structural elements. In the analysis, it is common for the structural engineers to consider a fixed base structure which means that the foundations and the underlying soil are assumed to be infinitely rigid. This assumption is not proper since the underlying soil in the near field often consists of soft soil layers that possess different properties and may behave nonlinearly leading to drastic variation of the seismic motion before hitting the structure foundation. In addition, the mutual interaction between the structure, its foundation and the underlying soil during the vibrations can substantially alter the structure response. This response variation depends on the structure characteristics, the soil properties and the nature of the seismic excitation. Consequently, an accurate assessment of inertial forces and displacements in structures requires a rational treatment of soil structure interaction (SSI) effects.

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.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
