| The fracture failure easily occurred at the traditional steel frame's rigid joints under seismic loading. So people began to look for and research a new type of joints—semi-rigid joints , through friction-type high-strength bolts and connecting pieces of the beam and column connected together, according to the research results have been know, the kinds of connections with stable performance hysteretic and the energy consumption of the good.According to the performance of semi-rigid connections, domestic and foreign experts and scholars began to study semi-rigid connections overall framework of dynamic performance, which ran the study is still in the start-up phase, no the theoretical basis for the relatively mature and experimental basis. Top and Seat angles with double Web Angles Semi-rigid Connections has obvious connections with the semi-rigid joints were referred to as non-linear characteristics of a typical form of semi-rigid connections, the paper related to the large number of reference literature at home and abroad on the basis of the kinds of forms connections the steel framework for the proposed pseudodynamic testing and research. Nodes on the overall framework of pseudodynamic testing in the main section contingency reaction force, changes in stiffness between layers, the layers framework acceleration response, each floor displacement reaction, response and basal shear layers hysteresis curve. The results show that: frame floors and displacement response acceleration response to better reflect the overall structure of the seismic performance of the engineering practice. And through rational design of Top and Seat angles with double Web Angles Semi-rigid Connections , under earthquake loading, semi-rigid framework will yield first in joints and the overall framework for a stable hysteretic behavior and good energy, the framework layer stiffness degradation the ground floor will be greater than the top speed.
