高强混凝土小型空心砌块墙抗震性能分析

High-strength concrete hollow block walls Seismic Analysis

高强混凝土小型空心砌块墙采用了强度大于MU15的高强砌块,并采用了高强度的灌芯混凝土(灌芯混凝土强度等级大于C30),还设置与芯柱混凝土强度等级相同的构造柱的配筋砌体。随着墙体材料改革的不断深入,混凝土小型空心砌块作为一种节能环保墙体材料得到了广泛的应用。但其在高层建筑中应用,特别是在抗震设防区的应用还存在一些问题。本文借助有限元软件ANSYS对高强混凝土小型空心砌块墙在不同砌块强度等级、不同混凝土强度芯柱-构造柱等参数下进行抗震性能分析,为其高层化发展,特别是在抗震设防区的高层砌体设计提供理论基础。

High-strength concrete hollow block walls using high-strength block strength is greater than MU15,and use of high strength grouted concrete（grouted concrete strength grade is greater than C30）,also set with the core columns the same strength grade of concrete structural columns of reinforced masonry.With the deepening of the reform of wall materials,concrete hollow block wall material as an environmentally friendly application widely.But its application in high-rise buildings in seismic areas,especially the application there are still some problems.With the help of finite element software ANSYS,high-strength concrete hollow block masonry walls at different intensity levels and different strength of concrete core columns-columns and other structural parameters,the seismic performance analysis,its high-rise development,especially in seismic zones theoretical basis for the design of high-level masonry.
