Abstract Near-field earthquake is one of the primary sources of ground motions that significantly affecting the structure's seismic response in its surrounding area containing pulse-long periods. The two popular and reliable approaches for the seismic investigation of structures are known as the force and displacement-based seismic design (FBD and DBD), extensively developed in the literature. In the present study, three types of steel buildings were defined for the seismic analysis, including five, eight, and fifteen-story steel buildings as the representatives of the multi-story, middle-rise, and small high-rise buildings, respectively. Steel structure designs and nonlinear analysis were done by implementing SAP2000 and Opensees software, respectively. The designed buildings were analyzed statistically and dynamically by performing the criteria determined in the FEMA-P750, Standard Code 2800, FEMA 356, and FEMA-P695, and then, FBD and DBD results were compared. The nonlinear static analysis results showed the acceptable displacements corresponding to the displacement criteria suggested by FEMA 356, showing the desirable performance of the designed structures. Also, the dynamic analysis results confirmed the reliability of the FEMA 356′s design criteria for the five and 8-story steel structures. However, the small high-rise building design has not met the regulations suggested by FEMA 356.
