混凝土小型空心砌块力学性能非线性模拟分析

Non-Linear Simulation Research on Mechanical Property of Concrete Small Hollow Block

混凝土小型空心砌块作为主要的墙体革新材料,主要表征是其力学性能,非线性有限元分析方法能实现构件从开始加载到破坏的全过程分析。基于有限元分析软件ANSYS,对混凝土空心砌块的力学性能作了数值模拟,分析了模拟结果,包括应变分析、应力分析、荷载位移曲线以及裂纹分析等。最后对混凝土空心砌块的非线性和线弹性的模拟结果进行了比对,为混凝土空心砌块的块型设计和优化设计提供参考依据。

As a kind of major wall material, the mechanical property features the concrete small hollow block. The way of non-linear finite element can achieve a complete process analysis from loading to failure. Based on the finite element software that is ANSYS, non-linear mechanical property of concrete small hollow block was simulated. Strain analysis, stress analysis, load- displacement curve and flow analysis were earied out. And simulation result of its non-linearity was compared with its line elastic. That will provide more useful help for shape and optimized design of concrete small hollow block.
