| Abstract: | The plane steel framework examples are studied as the mass-system model,two-winged fishbone-shaped model and the rod model separately.Natural and artificial seismic waves are exerted on the models,and the time history seismic responses are analyzed.The vibration model related to the structural stiffness matrix of mass-system model is determined with the anti-bend-point method,the D value method,the nonlinear static analysis method as well as the compliance method.The vibration model related to the structural stiffness matrix of two-winged fishbone-shaped model is determined with two-winged fishbone-shaped method.Then the vibration model related to the structural stiffness matrix of rod model is determined with the matrix displacement method.Results indicate that the matrix displacement method,the compliance method and the nonlinear static analysis method are more accurate,and the application conditions of anti-bend-point method are confirmed. |
| Keywords: | mass system model two-winged fishbone-shaped model rod model stiffness matrix time history analysis |
