This study analyzes the dynamic amplification factor (DAF) for highway bridges under moving loads. Five simply supported reinforced concrete girder bridges with span lengths from 20-40 meters are modeled in SAP2000. Static and dynamic responses like bending moment and displacement are computed for different vehicle velocities and IRC Class A and B loads. DAF is calculated as the ratio of maximum dynamic to static effects. Results show that DAF increases with rising vehicle speed, with a maximum of 2.47 for a 20m span under Class B load at 90kmph. DAF is also found to differ for Class A and B loads contrary to code specifications. It is concluded that vehicle velocity significantly impacts dynamic response and should be considered in DAF

Analysis of rc bridge decks for selected national a nd internationalstandard ...eSAT Journals
Abstract
The paper presents the comparison of the effect of different standard loadings on a set of reinforced concrete bridge decks using the
finite-element method. The parameters investigated include the aspect ratio (span/width) and type of loading. The investigations are
conducted on two lane slab bridge decks of span 5m to 9.5m and two lane T beam bridge decks of span 7.5m to 20m. A total of 36
bridge models were analyzed. The variation of different critical structural response parameters such as deflection, longitudinal
bending moment, transverse moment, shear force and torsional moments are evaluated for IRC loading (IRC Class A and 70R
loadings), AASHTO loading (HL93) and Euro standard loading (LM1). The results shows that the maximum difference in deflection
and longitudinal bending moment for the two IRC standard loading ranges from 5 to 15%. While the difference between
corresponding values for the AASHTO loading in the range of 5 to 17%. The maximum axle load of euro standard loading is found to
be 2.2 times higher than IRC class A loading maximum axle load hence the values of structural response parameters are increased by
1.7 to 1.8 times. Therefore there is a need for adopting simplified and more realistic standard loads in the future.

IRJET- Bridges’ Reliability between Specific Loading Case and Realistic TrafficIRJET Journal
This document discusses the reliability of reinforced concrete bridges under different loading conditions. The reliability index, which indicates the performance and probability of failure, is calculated for a set of bridges using both a standard truck loading model from code provisions and a realistic traffic loading model based on recorded weigh-in-motion data. The results show that using the standard truck loading leads to much lower reliability index values and more conservative/overestimations of failure probability compared to the realistic traffic loading model. On average, the reliability indices were about 140% higher when calculated using the realistic traffic data compared to the standard truck loading. Therefore, relying solely on standard code loadings for bridge evaluation may not provide accurate reliability assessments and could result in unnecessary maintenance or strengthening being

This document compares the linear static analysis and response spectrum analysis of a 3-storey educational building located in seismic zone 3 in India. The building was modeled in AutoCAD and analyzed in ETABS. Both analyses found higher displacement, bending moment, axial force, and shear force values from the linear static analysis compared to the response spectrum analysis. Specifically, the bending moment was 88.5% higher, axial force was 0.73% higher, and shear force was 43% higher from the linear static analysis. Therefore, the response spectrum analysis may provide a more accurate representation of the building's response during an earthquake and is recommended over the linear static analysis.

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

IRJET- Bridges’ Reliability between Specific Loading Case and Realistic TrafficIRJET Journal
This document discusses the reliability of reinforced concrete bridges under different loading conditions. The reliability index, which indicates the performance and probability of failure, is calculated for a set of bridges using both a standard truck loading model from code provisions and a realistic traffic loading model based on recorded weigh-in-motion data. The results show that using the standard truck loading leads to much lower reliability index values and more conservative/overestimations of failure probability compared to the realistic traffic loading model. On average, the reliability indices were about 140% higher when calculated using the realistic traffic data compared to the standard truck loading. Therefore, relying solely on standard code loadings for bridge evaluation may not provide accurate reliability assessments and could result in unnecessary maintenance or strengthening being

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELijaia
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
Road construction is not as easy as it seems to be, it includes various steps and it starts with its designing and
structure including the traffic volume consideration. Then base layer is done by bulldozers and levelers and after
base surface coating has to be done. For giving road a smooth surface with flexibility, Asphalt concrete is used.
Asphalt requires an aggregate sub base material layer, and then a base layer to be put into first place. Asphalt road
construction is formulated to support the heavy traffic load and climatic conditions. It is 100% recyclable and
saving non renewable natural resources.
With the advancement of technology, Asphalt technology gives assurance about the good drainage system and with
skid resistance it can be used where safety is necessary such as outsidethe schools.
