【摘要】 模网混凝土结构是一种新型的结构体系,其发展和应用顺应了我国墙体材料改革需要。为了实现其在我国地震区的推广和应用,本文对其抗震性能进行了分析和研究。本文对该结构体系的发展情况做了简要的介绍,阐述了非线性静力分析方法(Push-Over)的理论基础,并对本文所使用的各种软件的作用和特点一一作了介绍。首先,利用大型有限元通用软件ANSYS对几种不同规格的单面墙体的性能进行了建模分析。得出了在荷载作用下的荷载和位移结果,以及其裂缝和所受应变的分布图形。总结出这一新型复合材料的较为合理的本构关系。其次,运用总结出的模网混凝土墙体的本构关系,在ETABS建筑结构专用分析与设计软件中输入,对工程实例进行了模网混凝土剪力墙结构的整体抗震性能分析。并和PKPM系列的SATWE软件的计算结果进行了对比分析,证明了ETABS软件适用于设计模网混凝土结构。并通过大量算例总结出结构高度和墙肢轴压比对模网结构抗震性能的影响。最后,对以上的分析结果进行了总结,并提出了关于进一步深入研究模网混凝土结构技术的若干建议。

【Abstract】 Concrete structure with permanent shuttering kit is a new structural system whose developments and applications adapt well to the reformation of wall material in China. In order to realize the popularization and application of concrete structure with permanent shuttering kit in seismic zone, the seismic performance of this structure is discussed and analyzed in this paper.The developments of new structure styles are introduced in brief, as well as the theory of nonlinear static analysis (Push-Over). The software which is used in this paper are introduced.First, the finite element analysis of different scales of concrete wall with permanent shuttering kit is employed using the software of ANSYS, and then we get the result of the load effect which is under the displacement load, and the area of the crack and strain. Meanwhile, we have a reasonable constitutive relation for the new composites materials.Second, the analysis of the seismic performance of the concrete structure with permanent shuttering kit which has a new constitutive relation is employed using the software of ETABS. And we find that it is a reasonable way to analyze the new system. The method of the software is introduced particularly, which is compared with other software of SATWE. We also receive a conclusion that the height of the structure and the ratios of axial compression affect the seismic behavior of the structure.Finally, conclusions are educed according to the results. We suggest that we should improve the disquisition on concrete structure with permanent shuttering kit.
