The document compares the effect of seismic waves on multistoried buildings with and without shear walls and flanged concrete columns. Three 10-story building models are analyzed using STAAD Pro: Model 1 without seismic resisting structures, Model 2 with concentrically located shear walls along the exterior, and Model 3 with flanged concrete columns along the exterior.

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.

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

This document analyzes and compares the behavior of multistory buildings with shear walls and struts subjected to lateral loads. It finds that including shear walls and struts reduces displacement, drift, shear and increases stiffness compared to a normal reinforced concrete building. Shear walls alone reduce displacement and drift to a greater extent than a bare frame, and including additional struts leads to further reductions. The study concludes that a building with both shear walls and struts performs best in resisting seismic forces from lateral loads.
IRJET- Earthquake Resistant Design of Multistorey BuildingIRJET Journal
This document describes the earthquake resistant design of a 25-storey building using the software ETABS. It involves modeling the building, specifying materials and loads, and analyzing it for seismic load combinations according to Indian codes.

The frame columns are then replaced with shear walls and the analysis is repeated to compare the effects. The objectives are to minimize damage and loss of life from earthquakes by ensuring the structure can withstand strong ground shaking without collapse.

Study on the effect of special shear walls on seismic behaviour of multi- sto...IRJET Journal
This document reviews research on the effect of special shear walls on the seismic behavior of multi-storey reinforced concrete buildings. It summarizes 11 research papers that studied different shapes, sizes, locations, and configurations of shear walls. The key findings are that shear walls improve seismic performance by increasing stiffness and resisting lateral loads, but they must be designed to ensure adequate ductility. Locating shear walls at the corners or periphery of buildings generally provides the best seismic performance. Openings in shear walls can reduce seismic resistance, with up to 25% openings found to be acceptable without damage.

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.

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.
