Refined Simulation for Dynamic Damage Process of Single Layer Latticed Shell Based on Member Calculating Model
Based on mechanical characteristics of the single layer latticed shell member, two buckling types of structural compression members are summarized. The pre-buckling and post-buckling mechanical behaviors of the member are simulated by different calculating model, and the member calculating model are founded by which the likely buckle-straighten processes of the member and the form-disappear processes of the plastic hinge can be simulated. Numerical computing results indicate that based on the member calculating model presented in this paper, the changes of member mechanical behaviors and the consequent complex changes of structural bearing capacity in the seismic dynamic responses process of single layer latticed shell can be calculate accurately, and the refined simulation of the full-range dynamic response process for single layer latticed shell subject to dynamic excitation are realized.
