Abstract
This study investigates the behavior of concrete encased steel composite columns subjected to uniaxial compression straining actions. The experimental program consists of eleven specimens with total dimensions of 160x300x1900-mm; the selected schemes were specially chosen to consider the shear connectors effect, superposition analysis, derivation of exact interaction diagram, internal ties influence on ductility and strength, the composite action between the two materials. Comparisons of different codes approaches for the concrete encased steel composite columns have been introduced with the explanation of the experimental results taking into considerations the ultimate strength, ductility, strain energy, and flexure stiffness. It was concluded that the number of shear connecters is directly proportional to ultimate strength and ductility of the section, Also the confining effect is directly proportional to the ductility and ultimate strength. Comparison between experimental results and design guidelines has indicated that strain compatibility method provides the most accurate estimations
