The Shear Capacity and Improvement Measurements of RC Specially-Shaped Column Joints
Abstract eng: The joint shear capacity of RC specially-shaped column (SSC) structures in high intensity seismic zone was studied in this paper, and two measurements for improving joint shear capacity were put forward, there were vertical haunch in the beam end and embedded cold-formed steel in joint. ABAQUS software was employed for nonlinear finite element analysis of ordinary joints, joints with vertical haunch and with embedded cold-formed steel, taking tensile cracking, compressive crushing of concrete and yield of steel into account. Analysis results showed the improvement of shear capacity of joints with vertical haunch and with embedded cold-formed steel, revealed the change of failure mechanism and ductility, provided the foundation for practical design method.
