摘要
粉煤灰混凝土具有节约资源,提高混凝土工作性能的优点。为研究粉煤灰混凝土剪力墙抗震性能,本文以普通混凝土装配式剪力墙模型为基础,建立粉煤灰取代量为30%的剪力墙有限元模型,用大型通用有限元软件ABAQUS进行低周反复荷载模拟。同时考察轴压比、边缘构件配筋率、墙身配筋率等参数对模型的影响。结果表明,粉煤灰混凝土剪力墙同样满足抗震性能要求。
Fly ash concrete has the advantages of saving resources and improving the performanceof concrete.For the study of fly ash concrete shear wall seismic performance, based on the model ofcommon concrete assembled shear wall,a finite element model of shear wall with 30% replacement offly ash was established in this paper, simulation of low cycle cyclic loading with large general-purposefinite element software ABAQUS was made.The axial compression ratio, reinforcement ratio edge com-ponents, wall body reinforcement ratio and other parameters were investigated on the influence of themodel.The results show that the fly ash concrete shear wall also satisfies the requirement of seismicperformance.
