摘要
为研究单面叠合剪力墙不锈钢拉结件的抗剪性能,采用3种不同锚固端的拉结件,制作了 4个双侧抗剪试件,分别考虑施工阶段和使用阶段,进行了单向加载试验.对试件的破坏形态、承载能力等进行了研究.试验结果表明,不锈钢拉结件的抗剪性能较好,试件均发生混凝土锚固破坏,锚固端对试件抗剪承载力性能影响不显著.建立了抗剪承载力计算模型,并对试件抗剪承载力进行了计算,计算所得理论值与试验值吻合较好,并有一定的安全储备,可满足工程设计的要求.
Abstract
In order to study the shear performance of stainless steel tie members of single-sided composite shear wall,four bilateral shear specimens were made by using three kinds of tie members with different anchorage ends.Unidirectional loading tests were carried out considering the construction stage and the use stage respectively.The failure mode and bearing capacity of the specimens were studied.The test results show that the shear performance of stainless steel tie members is good,and the concrete anchorage failure occurs in all specimens.The anchorage end has no significant effect on the shear capacity performance of specimens.The calculation model of shear bearing capacity was established,and the shear bearing capacity of the specimen was calculated.The calculated theoretical value is in good agreement with the experimental value,and has a certain safety reserve,which can meet the requirements of engineering design.
