摘要
将混凝土作为非饱和多孔隙材料,利用混凝土损伤方程考虑多场耦合,建立混凝土高温损伤耦合模型。依据该模型,在有限元软件ANSYS的平台上进行混凝土高温损伤多场耦合仿真分析,模拟细观孔隙处应力云图,探讨高温对高性能混凝土的力学性能影响。
In this paper,concrete is used as the unsaturated porous material,and the multi-field coupling is considered by the concrete damage equation to establish a coupled model of high temperature damage of concrete.Based on this model,the multi-field coupling simulation analysis of high temperature damage of concrete is carried out on the platform of finite element software ANSYS,and the effect of high temperature on the mechanical properties of high performance concrete is discussed.
