Failure Mechanism of a Steel Frame under Oblique Seismic Action

Abstract:

Pushover anlysis of a three-story one-span space frame under oblique seismic action was conducted using ABAQUS software. The loading angle is 0°, 15°, 30° and 45° respectively. Failure mechanism of the space frame was analyzed, such as yield sequence of beam end and column end, and force-displacement curves. The results indicate that the structure loaded with angle of 0° failed when beam hinge appeared. With the increasing of load angle, the failure mechanism of frame changed from beam hinge failure to column hinge failure gradually.
