The Impact

This study discusses the impact of the vertical component of earthquake ground motion in the performance level of steel building subjected to earthquake excitations. Analyses are carried out for the strong column-weak beam philosophy because the structural performance is focused on these elements. A realistic steel frame is also considered to investigate the impact of including the seismic vertical component in the non-linear response of the building. The main findings of this study are: (1) When an analysis is performed by considering the horizontal and vertical components of ground motion acting simultaneously (near the causative fault), larger plastic rotations in the beams are obtained as compared to those resulting by considering only the horizontal component. (2) Due to the previous finding, if a codified criterion to inspect the steel beams performance in terms of the plastic rotation is considered, the beam performance could lie within a different acceptation criterion (i.e., from immediate occupancy to collapse prevention) if the vertical component is included in the analysis.

Column Base

The design of steel column base plays a very important role in steel structure design. Through large-scale analysis software ANSYS, this paper analyzes the steel column base by finite element numerical simulation nonlinear analysis,and discuss the fracture behavior and restoring force characteristics of steel pipe column in different thickness and axial compression ratio,and the link between the two. The results showed that, (1) the section of most likely break focus on the bottom of vertical load plane in the middle of the steel column base. (2) with the increase of thickness, anti-cracking ability increased gradually.(3) Axial compression ratio of the specimen has little effect for anti-cracking ability relatively. (4) With the increase of anti-cracking ability, the seismic behavior of specimens gets heightened.
