| 摘 要： | 上海中心大厦在长期荷载作用下结构竖向构件间的差异变形会在水平构件中产生较大的次内力。利用MIDAS软件的施工过程模拟功能,得到竖向构件在不同施工阶段的内力情况。通过混凝土B3模型,根据内力计算得到竖向变形。并将竖向变形施加到ETABS整体模型中的相应构件中,考察由于竖向构件之间的差异变形在相应的水平构件中产生次内力情况。在分析的过程中,比较了不同的水平构件连接方案对结构次内力的影响。分析结果表明：随着时间的推移,构件的竖向变形逐渐扩大,竖向差异变形在水平构件产生较大的次内力,工程设计中应该考虑此因素对结构的影响。图11表5参9

| Abstract: | The differential deformation between vertical structural members of the Shanghai Tower can cause secondary internal forces in horizontal structural members.In this paper,the construction process simulation feature of MIDAS was used to obtain the internal forces of vertical members at different construction stages of the Shanghai Tower.Through the concrete B3 model,the vertical deformation was calculated.The effect of the secondary internal forces of horizontal members were studied by applying the deformatio... |
