小砌块墙梁在周期荷载作用下的恢复力特性

THE RECOVERY BEHAVIOR OF SMALL UNIT MASONRY WALL-BEAM SUBJECTED TO CYCLIC LOAD

本文通过两片带芯柱的混凝土小砌块墙梁的试验研究和有限元分析,初步探讨了墙梁在水平周期荷载作用下的受力破坏机理和恢复力特性。提出了一些提高墙梁组合结构的抗震承载能力和变形能力的观点及措施。

The recovery behavlor and failure mechanism of small unit masonry wall-beam under horizontal cyclic load are studied, based on the tests of two specimens of small concrete unit masonry wall-beam with R.C.cores.Finite Element Analysis is also performed.Considerations and measures are presented to improve load-carrying capacity and deformational ductility for wall-beam composite structures.
