Abstract: The usage of composite materials has been increasing over the recent years. Characteristics such as high tensile resistance, erosion resistance and cost effectiveness are the reason of such trend. Using composite materials in concretes exposed to corrosive environments helps to increase the durability of the structure. The stirrups of a concrete structure, compared to longitudinal bars, due to closeness to concrete surface and less diameter are expected to have more defects in corrosive and acidic environments. In this study, an experimental and a finite element investigation is carried out on hysteresis behavior of T concrete connections for the effect of composite stirrup’s distance in the experimental part, a concrete connection is tested to calibrate the finite element model. Following that the experimental model was compared to and verified by the finite element model, using the finite element software ANSYS. Two groups of concrete connections, each including two connections are modeled by ANSYS. In each group, the variable is the steps of composite stirrups. Based on the results, connections with dense stirrup has 12% more capacity in compare to non-dense tied connections.
