摘要
以填充墙与框架结构共同作用为机理,通过分析在水平力作用下砖砌体填充墙—框架结构体系的自振周期,探讨填充墙对框架结构自振周期的影响程度及其规律,结果表明填充墙—框架结构体系的自振周期低于纯框架结构,有的甚至超出了设计常用修正值;在工程设计中应考虑填充墙对框架结构自振周期的影响,使框架结构在地震作用下的计算结果更切合实际,以提高结构设计的安全性与经济性。
Based on interaction of filling wall and frame structure, the self-vibration period of filling wall and frame structure has been analyzed under horizontal load and the influence extent of filling wall on self-vibration period of frame structure. It is revealed that the self-vibration period of filling wall and frame structure has decreased a little to simple frame structure. It has been pointed out that in the engineering design, the influence of filling wall should be taken into account, so that the computing of frame under earthquake is more accordant with the fact and the design is more safe and economic.
