| Abstract: | Large openings on floors of the multi-storied university gymnasium steel structure leads to the inhomogeneity of its mass and stiffness. In view of brace setting, nonlinear static push- over analysis method is applied to the structure with one large-scale finite element analysis soft- ware. According to the occurring sequence of the plastic hinges, the relationship curve between base shear and top displacement and the inter-story displacement angle etc. , collapse mechanism of the structure under serious earthquake is analyzed, and thereby the anti-quake performance target of the structure is deduced. |
