FINITE ELEMENT ANALYSIS OF CYCLIC LOADING BEHAVIOUR OF END-PLATE CONNECTIONS
Concerning the cyclic performance of end-plate connections,seldom finite element model exist. This paper built 3D finite element models,by using the general-purpose element software,ANSYS 11.0,to simulate and analyze the cyclic loading behaviour of 16 beam-column end-plate connections,in which different parameters such as end-plate thickness,bolt diameter,flush and extended end-plate,column stiffener,end-plate extension stiffener and the relative strength of the connection to the connected member were covered. In the model,all the plates were represented by solid elements and a combined hardening rule was used to simulate the material nonlinearity in the plasticity zone under cyclic loading. Further,contact pairs were adopted to model the boundary between end-plate and column flange. The bolt head was glued to column flange while the condition between the nut part and the end-plate was simulated with contact pairs. Pretension force in the high strength was modeled by using pretension element and the net area instead of the nominal diameter of the thread part was used. With comprehensive comparison between the results of the finite element models and the corresponding experimental tests,it can be concluded that the finite element model built in this paper can simulate the cyclic performance of the end-plate joint with amazing accuracy.
