混凝土灌芯纤维增强石膏板抗震性能的试验研究及有限元分析
|
摘要
近年来,随着人们对环保意识的增强及石膏板在工程中的成功应用,对石膏板相应的试验研究越来越多。然而,由于目前的建筑石膏板大多应用于室内吊顶装饰,或应用于非承重的隔墙等非承重构件,对于可用于室内外承重墙体的纤维增强石膏板的研究还不太成熟。
本文通过对14块混凝土灌芯纤维增强石膏板在低周反复荷载下的抗震性能试验,研究了不同灌芯形式纤维增强石膏板在低周反复荷载作用下的抗剪承载能力、变形能力和破坏特征;不同灌芯形式纤维增强石膏板在低周反复荷载作用下的延性、滞回特性、耗能能力、刚度退化规律等受力特性及抗震性能。通过试验分析,得出了满灌混凝土纤维增强石膏板类似于有连接键的带缝剪力墙结构,具有良好的抗震性能;隔孔灌混凝土纤维增强石膏板工作性能类似于组合砌体墙结构,且其抗震性能优于一般的组合砌体墙结构。
最后,本文利用非线性有限元方法对结构进行了力学分析,建立了切实有效的力学分析模型,为今后对各种结构尺寸的纤维增强石膏板进行计算机模拟试验提供了参考依据。
In Recent years, with the enhancement of the people’s environmental awareness and the successful application of plasterboard in the structure projects, more and more relevant research is focused on this topic for discussion. However, because most recent plasterboards are used in internal decoration such as ceiling suspension, or in non-structure components such as nonbearing walls and so on, there is little mature researches on fiber-reinforced plasterboard used as main wall.
This paper, by anti-seismic behavior experiments of fourteen 14 blocks of fiber-reinforced plasterboards filled with concrete under cyclic lateral loading, studied the capacity of shearing force and distortion, failed characteristics, the ductility and energy absorption of anti-seismic behavior of different concrete-filled styles under cyclic lateral loading, together with the research of the properties of rigidity degradation. This article draw a conclusion that the fiber-reinforced plasterboard fully filled with concrete is similar to the shear wall with slot; however, the one partly filled with concrete is similar to the composite brick masonry wall, and both have excellent anti-seismic behavior.
Besides, by using the nonlinear finite-element method, this article made a practical mechanic analysis model, offering a useful and effective reference for later computer simulative experiment of all kinds of specifications fiber-reinforced plasterboard.
