AB  - 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.
