钢结构抗震设计若干问题研究

On various issues of seismic design in steel structure

通过总结现行的规范和计算手册,研究钢结构强柱弱梁、强剪弱弯和强节点弱构件的一些要求。研究表明:规范对钢结构的强柱弱梁、强剪弱弯和强节点弱构件有一定的要求,且计算方法和混凝土结构有一定差异,但总体要求较混凝土结构明显降低,设计时应有选择性重视。

Through concluding current regulations and calculation handbook,the paper studies some steel steel structure demands of strong-column and weak-beam,strong-shearing and weak-bending and strong-joint and weak-member. The research shows that: the norm has certain demands for steel structure of strong-column and weak-beam,strong-shearing and weak-bending and strong-joint and weak-memeber. However,there is certain difference in the aspect of calculation method comparing to concrete structure. That is to say,comparing to concrete structure,its general demand obviously reduces,which should be selectively noticed in design process.
