| 摘 要： | 分析了某钢筋混凝土锯齿形排架结构设计中柱子截面取值偏小导致结构不满足承载力及变形要求的原因。将锯齿形排架与一般排架受力性能进行了对比研究,得出在锯齿形排架结构设计中不能将七字梁部分简化成链杆进行计算。针对工程特点制定了仅加固边柱的经济有效的加固措施。

| Abstract: | Column sections of a reinforced concrete zigzag bent frame structure are designed inadequate so that the bearing capacity and deformation can not be satisfied.The reason is analysed.A simple ordinary bent frame is compared with a zigzag bent frame to find the difference between them.The result indicates that 7-shaped beams can not be simplified to rigid bars during the design of a reinforced concrete zigzag bent frame structure.The effective measure that only exterior columns are strengthened is set down according to this project characteristic. |
