“结构控制体系”设计概念是近年发展起来的设计概念,是结构防灾减灾设计概念一次突破。 (二)分灾子结构 作为框-剪结构的分灾子结构,非灾害荷载作用下,带缝剪力墙能够满足正常使用要求 灾害荷载作用下,一方面利用带缝剪力墙的缝隙联结面材料进行耗能:另一方面,联结面开 裂,刚度降低,结构动力特性发生变化,周期变长,有利于结构抗震。框-桁结构,用一个 桁架代替剪力墙作为结构的分灾子结构。框-桁结构具有受力明确、计算简单、可人为控制 破坏顺序(弱腹杆→中强梁→强柱)、结构全部由杄件组成而不会出现刚度突变、可人为控制 刚度、不易造成材料浪费等优点 [参考文献] []陈向东,蔡文学基于分灾模式的结构防灾减灾设计概念初探自然灾害研究,1996(4):22-27 2 OU J P, YOSHIDA O, SOONG T T, et al.
