【摘要】 CS板式结构是一种很有推广前途的结构体系,其发展和应用顺应了我国墙体材料改革的需要。为了能够替代砖混结构,实现其在我国地震区的推广和应用,本文在已有试验成果和有限元分析理论的基础上,对CS板式结构的抗震性能进行了探讨和分析,并得到了CS墙板侧移刚度和内力的简化计算方法。首先,本文对新型结构体系的发展情况以及非线性静力分析方法(Push-Over)的理论基础作了简要介绍。提出了针对CS板中复合材料的均质化本构关系模型,并进行分析和论证,为CS板式结构的整体抗震性能分析建立了基础。其次,利用大型有限元分析软件ANSYS对某CS板式结构住宅进行了非线性静力有限元分析,并对其抗震性能进行了评估,得到了其抗震能力及适用范围。此外,与其他类似结构形式进行对比分析了该CS板式结构在水平荷载作用下的破坏机制及薄弱部位,为以后的设计工作提供依据。第三,对多种情况的CS墙板进行了有限元分析,得到了影响其抗震性能的主要因素。同时,对剪力墙结构的相关理论进行适当地调整得到了CS墙板的分类标准、侧移刚度及内力的计算方法,并讨论了CS板式结构侧移刚度与CS墙板侧移刚度之间的关系。最后,对以上分析结论进行了总结,并提出了提高CS板式结构抗震性能的措施和进行设计工作的建议。更多还原

【Abstract】 CS panel structure is a promising 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 CS panel structure as a substitute for masonry structure in seismic zone, the seismic performance of this structure was discussed and analyzed in this paper, basing on the experimental research of CS panel and finite element analysis. Meanwhile, the simplified computing methods for lateral stiffness and internal force were acquired.First, the developments of new structure styles were introduced in brief, as well as the theory of nonlinear static analysis (Push-Over). Homogeneous constitutive relations were proposed and confirmed for composite in the CS panel, as a basis of the seismic analysis and evaluation of CS panel structure. Second, the nonlinear static finite element analysis of a residential CS panel structure was employed using the software of ANSYS, and then its seismic performance was evaluated. Thus, its seismic bearing capacity and application scope were confirmed, as well as its failure characteristic and weak components, which are applicable to actual design.Third, through the finite element analysis on multiform CS wall panels, the factors concerned with their seismic behavior were indicated. The simplified computing methods for CS wall panel were defined too, including lateral stiffness, internal force as well as the criteria on the sorts of walls. In addition, the relationship between the stiffness of CS panel structure and that of CS wall panel was discussed.Finally, conclusions were educed according to the results gained, and then measures to improve the seismic performance of CS panel structure and the advice for design were given.更多还原
