This study aims to achieve the following goals: 1- To distinguish between the inelastic responses of buildings under earthquakes with NFGM and FFGM. 2- To inspect the effect of soil shear velocity on the response spectra. Several earthquake events, with different characteristics, are brought from the PEER website for “Pacific Earthquake Engineering Research” and analyzed using PRISM software to achieve these goals.
The research found that the acceleration, velocity, and displacement response of the selected near-fault ground motions on the structure has a higher effect than the far- field ground motion response in both types of soils and this difference is displayed more noticeably in long periods (periods after 0.2 sec). And when comparing responses of the two types of soils (the soft soil type and the rock type) it shows that the geological and geotechnical aspects of the soil deposits majorly affect the response spectra of the free field surface motions
