Physical properties such as displacement obtained by experimental methods in civil engineering structures and modal parameters contain important information about the current state of the structure. The determination of these parameters is usually done by the time history analysis of the data collected by acceleration, velocity and displacement. In order to determine the structure behavior under dynamic effects, a finite element analysis is often preferred. In this study, the effects of earthquake acceleration records applied in different ratios in the 3D steel frame system with semi-rigid joint are investigated. The analysis results reveal that the effect of semi-rigid connections on structural systems is significant. In the 3 storey steel frame with semi-rigid assembly, the effect of these connections on the system is presented numerically and visually. Comparison of the dynamic displacement of finite element model with experimental data has %99 achieved in good relation with visual inspection.
