摘要
混合结构由于材料性能差异,在施工过程和使用过程中存在一定的非线性变形差,对结构受力有一定的影响。结合某实际工程项目,采用MIDAS Gen进行施工过程及使用过程的模拟分析,分析中考虑混凝土收缩和徐变,研究结果有助于指导结构施工中竖向构件的下料长度和安全储备控制,有利于施工全过程的监测控制。
As a composite structure,steel pipe concrete frame-reinforced concrete core tube structure generates a certain nonlinear deformation difference in the process of construction and using,due to the differences of the material properties,which has a bad effect on the structural stress.Combined with a practical project,MIDAS Gen was used to make simulation analysis in construction process and using process,taking creep and shrinkage of concrete into account.The research results could provide reference for control the cutting length of the vertical member and safety storage,as well as the monitoring of the whole construction process.
