Nonlinear model of space structures and its application on seismic resistance

[摘要] Materially and geometrically nonlinear numerical model of space frame structures is presented. The eometrical nonlinearity covers loss of stability through buckling, screwing or protrusion of girder elements, and the material nonlinearity follows the stre
