Linear time history analysis of steel structures and the effect of spectrum matching parameters

In recent years, the development of technology and good engineering methods have led to better determination of the behavior of the structures under seismic loads. Nonetheless, non-linear behavior analysis methods are preferred by the engineers. In this study, the sections of SAC model 3-9-20 storey LA buildings defined in FEMA 355-C Appendix-B were optimized and analyzed on the moment steel frame system. In our study, the results of the general behaviors were analyzed by using the linear calculation method in time domain according to 3 different spectrum types (Elastic Spectrum, Inelastic Spectrum according to TBDY 2018 and Inelastic Spectrum according to ASCE). Earthquake behavior of 3 different levels of buildings (ZA-ZB-ZC-ZD), 3 different spectrum types and 7 different earthquakes were recorded. In this review, different lateral load combinations were considered. These structures were analyzed according to a response spectrum. Analyzes were made in Sap2000 program. In these analyzes, the charts of the force values of the three different spectra and the response spectrum of the base of the spectrum and the tables of the relative floor translation were prepared.
