摘要
基于ANSYS软件对混凝土空心砌块砌体进行非线性有限元分析,主要研究混凝土的本构关系、混凝土的强度等级和砌块孔型对砌块力学特性的影响,同时对两种不同孔型的砌块砌筑成的砌体进行有限元分析,发现在相同外荷载和约束情况下,Ⅱ型砌体中砂浆的受力明显好于I型,且Ⅱ型砌体中应力分布比I型砌体更为合理,该分析方法将为混凝土空心砌块砌体的进一步应用提供参考依据。
Based on software of ANSYS, non-linear finite element analysis is utilized to the concrete hollow block and bricking-up, mechanics characteristics influence are analyzed including stress-strain relations of concrete, concrete intensity rank and brick pass. simultaneously.The finite element analysis is used to two kinds of pass artificial brick masonry and building, discovering II bricking-up mortar stress obvious superior to I under the same load, and II bricking-up stress distributes more reasonable to I, the method will offer more useful assitance for mechanics property and optimized design of concrete hollow block and bricking-up.
