Influence on Seismic Performance of Joints of Cellular Steel Column and Steel Beam due to the Opening Rate

Article Preview

Abstract:

The article researches seismic performance of joints of cellular steel column and steel beam by finite element simulation. Finite element model is established by using the finite element software reasonably. Considering about the hole position and the distance of center of hole as invariant moments, under low cyclic loading we can attain hysteretic curves and skeleton curves etc. which are compared and analyzed in different opening rate by simulated software. The results show that for a certain axial compression ratio (n=0.45) of joints of cellular steel column and beam, the reasonable opening rate can improve the seismic behavior of the joints.
