Abstract

Steel concrete composite structures are widely used in many structural applications such as beams, slabs, walls and columns. Composite structures provide not only great reduction for the element size and weight but also high structural efficiency. Because of the little data and disagreement between the R.C. and steel Egyptian Codes of Practice, an experimental and theoretical investigation were conducted to study the behavior of concrete filled steel box columns. The experimental program consists of six square filled steel box columns and two square R.C. columns (reference elements). The experimental variables are the load position (centric or eccentric) and the distribution of the mechanical shear connectors (nails). Test results are presented and discussed in comparison with the estimated values predicated from the Egyptian R.C. and steel codes of practice as well as the values obtained from the finite element program (ANSYS 12).
