Seismic Examination (G+5) Working with and without Propping

Abstract

An earthquake is a natural event that occurs and causes extensive damage; therefore, it is necessary to limit the damage caused by earthquakes in order to overcome shortcomings in the ability to resist seismic stresses. The best strategy for resisting wind and seismic forces is bracing. The seismic performance of a (G+5) storey structure with and without bracing was determined using SAP2000 Software in this study. Analyzing several types of bracing, such like diagonal, X-bracing, V-bracing, and inverted V-bracing, was used to conduct a comparison analysis. When compared to other frames, the diagonal and Inverted V bracings have less lateral displacements, according to the observations.. The seismic performances were then evaluated using time history analysis for bare frame, diagonal, and bare frame. The findings of base shear, storey displacement, and storey drifts were computed and compared to those of manual calculations. The braced frame is more resistant to seismic excitation than frames without bracings. When compared to un-braced frames, storey displacement and drifts are minimized, according to the study's base shear value. The results of manual calculations were contrasted with the computed base shear, storey displacement, and storey drifts. Compared to frames without bracings, the braced frame is more robust to seismic excitation. The study's base shear value indicates that storey displacement and drifts are reduced in comparison to unbraced frames.
