摘要
Abstract
For the large-scale corner-configured single-cable curtain wall structure in the 5-story atrium space without columns from the 17th floor to the roof of the CSCEC International Headquarters project,several structural design challenges were encountered,including ultra-long overhangs,elastic boundary supports of cables,and tensile stresses in vertical concrete components.To address these issues,a systematic simulation study was conducted,focusing on key technical aspects such as selection of supporting boundary structures for the cable-supported curtain wall,response and balance of tensile stresses in concrete vertical members,synergistic interaction between supporting boundaries and cable structures,and the effects of concrete shrinkage and creep.The results indicate that tube-top point-supported truss scheme significantly reduces concrete damage at the supports while lowering construction difficulty and costs.The application of retard-bonded prestressing technology and the incorporation of steel in supporting columns effectively mitigate tensile stresses in concrete vertical members.The nonlinear behavior of the curtain wall cables considerably influences the seismic response of the main structure,indicating that seismic design should be based on time-history analysis of an integrated structural model including the cables.Concrete shrinkage and creep exert a substantial impact on the cable-supported curtain wall,highlighting the importance of monitoring cable forces during the service phase.关键词
