Seismic Behavior Analysis of Beam-Column Joints of Steel Structure Semirigid


Article Preview

In order to study the seismic behavior of steel frame structure, based on the verification of the finite element program, two different end-plate connections under monotonic load and cyclic load are analysed with the finite-element software ANSYS, considering geometry, material and status nonlinearity. Some parameters such as height of endplate, array of blot, diameter of blot are analysed to study their effects on the seismic behavior of beam-to-column end-plate connection, the bearing capacity of the joint of the framework, the initial rotation stiffness, the ultimate turning power, power-wasting capacity and ductility. The results show that reasonable connection have better power-wasting capacity and ductility , so it can be applicated in multiple-story steel frame structure.
