Abstract

This paper presents an Experimental investigation for push out tests to determine the shear strength and the load-slip curves of a new shape of the shear connector results from the reforming of the steel cold formed section (CFS). This new shear connector has been used previously in our researches (under publication) to achieve the composite action in composite cold formed steel beams. Seven push out specimens are tested so as to make a parametric study to determine the effect of the variation of different parameters on the strength of the shear connector, the steel section consists of two cold formed steel channel sections back to back of thickness ( tst ) and 30 cm height and yield strength  ( fy ) which connected to a reinforced concrete columns (15cm *15cm) of 30 cm height of compressive strength ( fcu ) using means of new shear connector ,the new shear connector is developed from the reforming of a part of the steel section flange so as to be embedded inside the concrete to resist slippage between steel and concrete.
The studied parameters are the compressive strength of the concrete (fcu), the yield strength of the steel (fy), the breadth of the shear connector (b), the height of the shear connector (h) and the thickness of the steel (tst)
A finite element model has been used to simulate the behavior of the real test so as we will be able to study more parameters with more variations using ABAQUS/CAE, and also an empirical formula can derive to calculate the strength of the suggested shear connectors
