Calculation of moment resistance of semi-rigid steel-concrete composite joints

In the semi rigid steel concrete composite joints, the slab reinforcement enhances the resistance and stiffness of the joints, but the traditional design approaches generally overlook the actual joint response and adopt simplified analysis models. Consequently,simplified design rules based on a complete understanding of the joint behavior should be used in order to take into account the economic benefits. In this paper, a calculation method is introduced to predict the flexural resistance of semi rigid steel concrete composite joints. The proposed formulas consider the effects of the slab reinforcement on the flexural resistance. The calculated results show good agreement with the test results. The research results presented in this paper will be valuable for engineering practice and revising code.
