| 摘 要： | 在施工期间,框架结构中框架柱之间轴压比的不同以及混凝土收缩和徐变的存在,造成了构件之间存在竖向变形差异,进而会对框架结构中梁柱内力产生重要的影响.本文以一栋框架结构高层建筑为分析对象,分析了施工过程及收缩徐变对框架结构竖向变形及内力的影响,并在此基础上对结构分析及设计提出了一些有用的建议.

| Abstract: | During the period of construction,shrinkage and creep of concrete and different axial compression ratio result in the difference on vertical deformation between columns of frame structure.And then the difference imposes a great effect on the internal force of beams and columns in frame structure.In the paper,analysis were carried out on the effect of construction procedure and shrinkage and creep of concrete on the vertical deformation and internal force of a high building of frame structure and some conclu... |
