Numerical Analysis on Seismic Performance of Beam-Column Joint in the Added-Layers Steel Structure

Abstract:

Using ANSYS for the three add-layers beam-column joints to non-linear analysis their seismic performance.The results showed that: Model’s hysteresis curve all showed a square spindle-shaped, smooth and full curve, but find the "pinched rope" phenomenon, and have strong energy dissipating capacity;The joint reinforced by Haunched plate has strong bearing capacity, stiffness and energy dissipating capacity, meanwhile, this type of joint contains highest yield strength, largest hysteresis loop area and ductility factor, and has good ductility and energy dissipating capacity. So, it can be used in the earthquake area;The local damage of these joints are start at one point, and out gradually spread. The first joint’s beam-column connection point destruction firstly, and the joint lose its bearing capacity because the components off each other. The third type of joint formed plastic hinges during the process of loading, plastic hinges can change the failure mode of the joint.
