不同厚度钢筋混凝土筏板基础的温度应力仿真

Thermal Stress simulation of RC Foundations with Different Raft Thicknesses

利用有限元软件ANSYS对4种不同厚度钢筋混凝土筏板基础的水化热温度场及温度应力进行了仿真,给出了具有代表性节点的温度及应力变化曲线,在分析筏板厚度对温度应力影响的基础上,提出了控制混凝土温度应力的相关建议.

By means of ANSYS, this paper simulated the thermal fields and stresses of hydration heat in RC （reinforced concrete） foundations with four different thicknesses, which resulted in the curves of temperature and stress variations of effects of the raft thickness on the thermal in some stress, representative joints. Based on analysis relevant suggertions were presented for controlling the temperature stress of concrete.
