基于抗震概念设计的密肋复合墙新型抗震结构体系
|
摘要
以512汶川大地震震害调查为基础,从抗震概念设计的角度出发,对建筑结构的典型震害进行了分析,指出设置多道防线、合理刚度布置、增强整体性能、重视非结构构件等对于保证结构抗震安全的重要意义,并结合课题组多年的研究成果,提出了一种具备多道抗震防线的刚度可调型密肋复合墙新型抗震结构体系,探讨了其对于改善结构抗震性能所起的积极作用.
Based on the seismic damage investigation of Wenchuan earthquake,the typical seismic damage of building structures is analyzed in the view of seismic concept design.The results indicate that it is significant to set multiple fortifications,arrange reasonable stiffness and strengthen the utility and accessory components of the buildings.And according to the former research,a new seismic structure of multi-ribbed composite wall is put forward and discussed,which has the benefits in seismic performance with multiple fortifications and adjustable stiffness.
