摘要
通过对高层建筑结构工程整体计算中竖向构件在竖向荷载作用下的内力分布变化的分析,揭示了竖向构件间结构变形协调的抗力机制,提出了完整建筑结构设计需经历结构变形协调分析、结构易损性分析及结构鲁棒性分析等三个层次的新思路,并建立了在竖向荷载作用下的结构变形协调模型、结构易损性模型及结构鲁棒性模型。
Through the analysis of the changes of the internal forces of the vertical components under the vertical load in the high-rise building structural engineering model,the force transmission mechanism of the vertical deformation compatibility between the vertical components was revealed.Three levels of new analysis ideas in the whole design of building structures were proposed,which were the analysis of the structural deformation compatibility,the structural vulnerability and the structural robustness.Also structural models were built for the analysis of the structural deformation compatibility,the structural vulnerability and the structural robustness under vertical loads.
