Study on Composite Column Under Monotonic and Cyclic Loading

Abstract

Nowadays, composite beams and columns were used as structural members for their higher strength and rigidity for load-carrying structures. Generally, the concrete-encased composite column has a compound section formed by the steel section and the surrounding concrete will be made by a composite. Based on the studies of steel encased concrete sections based on experimental and computational analysis over static and dynamic load cases shows advantages over the conventionally use structural steel or reinforced concrete in terms of ductility and shear resistance. The structure can experience static loads as well as fatigue loads in some situations. So the behavior of structural elements under differential loading should be obtained to design them effectively. A similar shape of the column section plays a key role in resisting lateral buckling under axial compression. This paper compares the behaviour of steel concrete composite sections by varying the shape and size for both concrete infilled and encased conditions based on the earlier research works.
