| 摘 要： | 我国建筑结构抗震设计主要采用基于小震下的构件承载力计算保证结构的抗震承载能力,配合抗震构造措施保证结构的变形能力,缺乏大震抗倒塌定量计算.而实际地震震害表明,即使是同类结构,其结构体系参数对其抗地震倒塌能力也有很大影响.为此,本文依据《建筑抗震设计规范》GB50011 - 2001,按照7度抗震设防设计了24个不同跨度...

| Abstract: | The seismic design of Chinese building structures is mostly depended on the structural elemental loading capacity design under minor earthquake and the detailed design to ensure the deformation capacity.However,it is lack of quantitative analysis of seismic collapse resistance under severe earthquake.And the actual seismic damage shows that even for the same structural types,the global structural parameters will greatly influence the seismic collapse resistances.Therefore,this paper designs 24 RC frame stru... |
