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．
