约束砌体结构的抗震性能与设计方法
|
摘要
为提高砌体结构的抗震强度,改善其延性,扩大其应用范围,提出采用约束构件包围砌体,构成钢筋混凝土─砌体组合墙共同承重的结构新体系。经研究和分析,约束砌体的抗震强度有明显的提高,延性有显著的改善,它是一种既经济,抗震性能又好的结构形式。本文的研究成果,可为拟建砌体结构的抗震设计和对现役砌体的抗震加固提供科学依据;同时,也适用于其它各类砌体建筑。
For increase the seismic strength and improve the ductility and expand the applied range of masonry structure, the binding members are used to encircle the masonry for forming a common bearing new structural system on combined wall by reinforced concrete and masonry. After study and analysis, the binding masonry structure is a kind of better structure system in economy and earthquake-resistant behavior with the notable seismic strength and the ductility. The study achievements on this paper can be used to anti-seismic design for the drafting masonry structure and anti-seismic reinforcement for the active duty masonry structure,and also to be suitable for the other kind of masonry structure.
