带芯柱陶粒混凝土砌块墙体抗侧力性能

本文通过八片设置芯柱的陶粒混凝土砌块内、外承重墙体的恢复力试验,讨论了这种墙体的破坏机理,分析了芯柱、正应力和其它一些因素对墙体的抗侧承载力、变形能力的影响。根据试验和分析,提出了这种墙体的抗震承载力计算方法。

Testing and Analyses of the Aseismatic Behaviour of Ceramsite Concrete Block Masonry with Core R/C

The experimental results of eight ceramsite concrete beating walls with core R/C are presented.The failure models of walls under cyclic lateral loading are discussed. The effects of compressive stress, core R/C and other different factors on the shear strength and deformation behaviour are analysed. Furthermore, the restoring force model and the elastoplastic characteristic parameters are also given in the paper. On the basks of the tests and analyses,the formulae for shear strength of this kind of wails are proposed.
