摘要
以现行框架设计方法为基础,提出了一种新型的摇摆填充墙-框架结构,通过构造措施可以彻底改变框架结构的层破坏机制。采用静力非线性分析,对摇摆填充墙-框架结构、普通填充墙-框架结构和纯框架结构的抗震性能进行对比分析,结果表明:摇摆填充墙-框架结构在墙体摇摆之前其性能与普通填充墙-框架基本相同,在墙体摇摆之后能够改变结构层间变形分布,使结构层间变形趋于均匀,结构破坏机制变为整体型破坏,有效提高了框架结构的延性性能。
A new rocking infilled wall-frame structure is proposed on the basis of the current framework design method, Through the structural measures, the layer failure mechanism of frame structure can completely be changed. Pushover analysis is carried out to clarify difference among the RC fame, simple infilled wall-frame and rocking infilled wall-frame structures. The results show that the rocking infilled wall-frame structure can significantly change the deformation distribution between the layers, more uniformly distributed, and the failure mechanism is into the overall damage. And the same time the rocking infilled wall can also efficiently improve the ductility and energy dissipation capacity of the frame structure.
