施工中结构全过程模拟弹塑性时程的分析

某连体结构工程,利用NosaCAD有限元软件建模,转换生成包括施工模拟分析和弹塑性时程分析参数的ABAQUS有限元模型,对结构进行7度罕遇地震下的弹塑性时程分析,得到结构位移、层间位移角及混凝土损伤分布等情况。结果表明:罕遇地震作用下,结构最大层间位移角满足1/100的限值要求,结构构件损坏顺序和分布合理。

ELASTO-PLASTIC TIME HISTORY ANALYSIS OF STRUCTURE AND CONSTRUCTION

Aiming at a double-tower connected structure,which model was built with NosaCAD and was transferred into ABAQUS finite-element model,construction simulation analysis and elasto-plastic time history analysis were performed. Based on behavior of the structure under rare earthquakes with intensity 7,the displacement,inter-story drifts and distribution of concrete damage patterns of the structure are obtained. The result indicates that under rare earthquakes,the maximum inter-story drifts satisfied the requirement of the Chinese seismic design code. The order and distribution of damage in the components are reasonable.
