基于FEM和应力迹线可视化的地下室不均匀膨胀效应研究
Research on Uneven Expansion Effect of Basement Based on FEM and Stress Trajectory Visualization
摘要
Abstract
Based on the concrete basement structure of Nanchang modern service Industrial Park,in this paper,the Abaqus refined model is established by using the sunshine temperature field simulation theory.The simulation results of temperature field are compared with the meas-ured data,and the basic law of sunshine temperature field in the basement is analyzed;Parameter analysis was carried out to compare the dis-placement stress response of complete concrete basement structure.The results show that the uneven expansion effect is easy to cause the side-wall to crack in the shape of"八".During summer construction,measures shall be taken in time to avoid excessive temperature gradients be-tween the upper and lower parts of the structure.关键词
