再生混凝土砌块墙体抗震性能试验研究
|
摘要
为研究再生混凝土砌块墙体的抗震性能,对4榀构造柱-圈梁体系约束的再生混凝土小型空心砌块墙体试件进行了低周反复水平加载试验,研究了再生混凝土砌块墙体的破坏过程、破坏形态、承载能力、变形能力和耗能能力等,分析了构造柱-圈梁约束体系与砌块墙体之间的相互作用机理及破坏机制。研究表明:符合构造要求的再生混凝土砌块墙体具有良好的延性和耗能能力;提高构造柱纵筋配筋率,并不能有效改善再生混凝土砌块墙体的抗震性能;按现行规范公式计算再生混凝土砌块墙体的受剪承载力是可行的;按照普通混凝土砌块承重结构的抗震设计要求,可以实现再生混凝土砌块承重结构与普通混凝土砌块相同的抗震性能。
In order to study the seismic behavior of the recycled concrete block wall,four recycled concrete small-sized hollow block walls confined by tie column-beam systems were tested under low cyclic horizontal loadings.Based on the experiment,the damage process,failure mode,load carrying capacity,deformation ability and energy dissipation are studied.The interaction mechanism between the recycled concrete block masonry wall and the tie column-beam confined system are investigated.The test results indicate that the recycled concrete block wall has good ductility and energy dissipation capacity,and increasing the reinforcement ratio of tie columns cannot effectively improve the seismic performance of walls.Furthermore,it is reliable to calculate the shear capacity of the recycled concrete block wall according to the current codes.If the recycled concrete block walls are designed according to the basic seismic requirements for normal concrete block walls,the seismic performance of recycled concrete block walls is similar to that of normal concrete block walls.
