| Abstract: | For the problem of concrete-filled squared tubular column connected to steel beam,the deformability of the rigid joint with lugged through flange diaphragm and wedge filter is researched.3D finite element models are established;and the Von-Mises failure criterion and bilinear kinematical hardening stress-strain relationships are used for steel and the elastoplastic stress-strain relationships is used for concrete.Hysteresis behavior of the joints under cyclic loading is analyzed on the basis of nonlinear finite element method;aseismic behavior indexes of the joints is researched and compared;and the result of nonlinear finile element analysis can provide a reference for engineering design. |
