“…In case of prefabricated composite column, the ultimate strength and deformation capacity will be higher than that of the conventional reinforced concrete columns. The increase in flexural strength and energy absorption at composite columns may be assumed due to the design loads considered during the design of bolted connections for precast construction [4,9,10,11]. During the cyclic test energy absorption capacity under the prestress effects of the specimens were recorded in the load cells.…”

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.

“…It was found that when the stirrup ratio is increased obtained a better seismic behavior, the composite columns with cross-shaped steel have better seismic performance than those with H-shaped steel, and the minimum value can be 2.5 of the embedded ratio of steel concrete composite columns. Campian et al [2] Conducted tests of composite encased columns with high strength concrete and comparison the results with normal strength concrete, the results show that the columns with high strength concrete is more susceptible to fragile failure than the normal concrete and the high strength has a favorable energy absorption capacity. Zhu et al [3] Carried out the effects of stirrup arrangement and structural steel details with studs and study the behavior of the steel reinforced high strength concrete columns (SRHC) under cyclic load by experientially test twenty on of SRHC columns.…”

Concrete and steel have different advantages, concrete has high compression strength and low cost while steel has high tensile strength, rigidity and ductility. Composite members have other beneficial qualities beside all of them. Composite columns are used extensively in modern buildings essentially in industrial buildings. The main purpose of this study is an analysis and a comparison between the responses (load‐displacements) of different types of composite columns under cyclic loads. For this purpose, a three‐dimensional (3D) finite element model is developed for the columns, the finite element analysis of composite columns is carried out by using ANSYS code. The numerical model considers the elasto‐plasticity of materials and the non‐linearity of contact friction. It is interesting to observe a large ductility of these composite elements and the efficiency of some types of the composite columns than others. The aim of the study is to analyze the encased composite columns under cyclic loads focused on the different type of steel section. The parameters studied are the influence of axial load levels, skeleton curve, ductility, energy dissipation and the peak lateral load also carried out. The results indicate that the first columns of the specimens have a low specimen energy dissipation due the durability of the columns is higher than the axial load applied, and for better ductility and energy dissipation the axial load level of fully encased composite columns should be limited to approximately a value of 0.6.

“…The ultimate flexural stiffness, ductility, and strength absorption capacity can may be enhanced by offering the cross ties and reduced spacing of the hoops. This is attributed often to the expanded confinement furnished through the way of transverse reinforcement [1]. Chen, Li, & Weng, have proved by tests that by resisting concrete flexural and concrete shear cracking that occurs due to increased axial compression of steel and concrete composite column, joint behavior improves.…”

Modern day construction is widely influenced using Steel-Concrete composite columns. The rapid growth in Steel-Concrete composite construction has significantly reduced the use of conventional Reinforced Cement Concrete (R.C.C) as well as other steel construction practices. Steel-Concrete composite construction gained an extensive receiving around the globe. Considering the fact that R.C.C construction is most suitable and economic for low-rise construction so it is used in framing system in most structures. However; increased dead load, span restriction, less stiffness and risky formwork makes R.C.C construction uneconomical and not suitable when it comes to intermediate to high-rise buildings. One Basement and 11 storeys existing building has been analyzed and comparison has been made between R.CC structure and concrete steel composite columns. Equivalent Static non -linear analysis was performed in X and Y direction by using Etabs 2017 software which results that encased composite columns construction cost is more than R.
