带多构造柱砖墙的变形性能分析研究

On deformation behaviour of the masonry wall with multi-columns

通过带边框构造柱与带多构造柱砖墙的１：２模型在低周交变荷载下的对比试验，研究了墙片开裂至破坏的全过程，着重分析了刚度、延性及耗能等问题。试验结果表明，在带边框构造柱的墙体中再增加构造柱后，既能较大幅度地提高抗裂度和承载力，又能明显地改善变形、延性及耗能性能，从而给带多构造柱的墙体在抗震工程中的应用提供了理论和试验依据。

By the comparative test of 1: 2 models for the brick masonry wall with edge--frame columns andthat with multi-columns under low-cyclic loading,the whole process that the masonry wail is destroyedfrom cracking to failure is investigated.The paper studies the problems of stiffness. ductility,energy' dissipation and so on. The test results indicate that by adding columns in the masonry wall with edge-framecolumns,the anti-cracking degree and the load-bearing ability of the wall not only can be increased,but thebehavior of deformation,the ductility and energy dissipation of the wall can be improved evidently also.Therefore it provides some bases of both theory and test for the application of the masonry wall in aseismicengeneering.
