Non-linear Analysis of Multistorey Structure having Different Plan irregularities using Etabs

Because earthquakes cause significant harm and losses in terms of human life, loss or damage to structures, and loss of the economic or financial system, seismic building analysis is one of the research topics of interest today. In order to prevent seismic effects by building structures to withstand earthquakes, it is desirable to investigate seismic response with real-time history. In this study, four different vertically irregular building models were examined. Each model was examined for three different situations: without mass irregularity, with mass irregularity growing from bottom to top, and with mass irregularity decreasing from bottom to top. Building kinds and building analysis types are introduced at the beginning of the current study project. The study and examination of already published material and theories follows the introduction. It is also examined how time history analysis relates to other types of analysis. The issue is then identified; it consists of all chosen and decided-upon building parameters as well as the type of analysis to be taken into account. The research's goal is specified, and a thorough explanation of the methodology to be used is provided. Vertical irregular problem analysis with respect to time history analysis is the method used. In order to undertake and conduct research work, four building models with five-time history reference data were taken into consideration. For deflection, overturning moment, drift, and base shear, the data gathering is then primarily organized in a tabular fashion. The results of the entire building analysis are grouped together. Analysis based on time history is put to the test for vertically uneven buildings and cases. Graphs are used to describe the results and the conversation, and each graph's conclusion and analytical summary was determined by critically analyzing and studying it. All of the data that was gathered for each scenario that was addressed in the issue and objective were plotted on graphs.
