预应力混凝土砌块砌体抗裂性能的有限元分析

Finite element analysis to crack-resistance behavior of prestressed concrete block masonry

通过Ansys有限元分析软件,针对不同类型的预应力混凝土小型空心砌块墙体建立相应的有限元模型,并对其抗裂性能进行了分析计算,得到了水平荷载作用下墙体的应力分布规律及其开裂形态,为预应力混凝土小型空心砌块砌体的应用提供了理论依据。

Adopt finite element analysis soft,we established different types of prestressed masonry models and studied the crack-resistance behavior of prestressed concrete block masonry,and get the law of stress distribution and crack shape in the wall,which will provide us the theoretic basis to use of the prestressed masonry in engineering.
