Frame structures. steel-concrete composite structures versus traditional ones

Abstract

The paper presents a case study performed on composite structures made with fully encased steel-concrete composite columns and steel beams. The structures chosen for the case study have the same floor plan, but different height. For every type of composite structure were design three types of composite columns, using different structural steel ratios: low, medium and high. Seismic analysis was performed on the studied frames to determinate structure performances and also an economical study was realised from structural steel ratio point of view. In the end of the paper the composite solution is compared with traditional reinforced concrete and steel ones.
