Pushover analysis on steel-concrete composite frames

Abstract

The paper presents a case study performed on five types of similar steel-concrete composite frames, with different heights: two, six, eight, ten, and twelve levels. The composite frames are made with fully encased steel-concrete composite columns and steel beams. For every type of composite structure designed three types of composite columns were, using different structural steel ratios: low, medium, and high. To study the seismic performances of studied frames pushover analyses were performed on the chosen structures. Some conclusions extracted from the performed analysis were drawn at the end of the paper.
