Abstract
AbstractThe structures are designed for a much lower force than maximum force if the structure remains elastic, with the expectation of the building undergoing damage in case of strong shaking, ductility will play a major factor in post-yield behavior. Current equivalent static method in Indian Seismic code uses response reduction factor based on building system for calculating seismic horizontal coefficient which integrates with a total weight of building to give design force as output. The performance-based plastic design method directly accounts for the inelastic behavior of structure, thus eliminating any post-assessment or iteration after the initial design. Two model frames, 4 and 8 stories, are designed based on equivalent static method IS 1893 Part 1 (2016) and performance-based plastic design. The evaluation of this model is extensively done by nonlinear static pushover analysis. By comparing the results, the incorporation of inelastic behavior shows a higher response reduction factor concerning the factor given by the Indian Seismic code as per different building structures.KeywordsPerformance-based plastic designPost-yield behavior
