摘要:
体外预应力混凝土结构在新建结构和旧有结构加固方面得到了广泛运用,由于其体外索和梁体在受力过程中变形不相协调的特点使计算比较困难,采用有限元进行数值分析是常用的一种方法.体外预应力混凝土结构有限元建模有其特殊性,如何建立有限元模型是正确分析的基础.本文详细介绍了如何运用ANSYS对体外体外预应力混凝土简支梁进行有限元建模及全过程分析,包括单元选取、本构关系的选用、网络的划分、计算的设置等,最后通过实例验证了该建模方法的正确性.
Abstract:
External perstressed concrete structures have been widely used in new buildings and reinforcement of old buildings. Because the deformation of prestressing tendon and the beam is not compatible, it is difficult to calculate. Finite element analysis is a common calculational method. Modeling of finite element analysis of external prestressed concrete beam has its particularity. How to build the model is the basis of the proper analysis. In this paper,how to build the model of the external prestressed concrete beam by ANSYS was introduced in detail, including how to select element, how to select constitutive relation, division of lattice, setting of calculation etc. An example was given to verify the accuracy of the modeling method at last.
