摘要
带主楼地下室抗浮锚杆按常规布置方法设计不能考虑主楼和地下室刚度对锚杆内力的贡献,均匀布置的锚杆实际受力是不均匀的,部分锚杆的实际承载力大于常规方法设计的结果。主楼与纯地下室结构底板刚度变化较大,采用有限元软件进行抗浮整体计算分析发现,按变刚度设计方法进行抗浮设计,可使锚杆和底板的受力达到最优。
The anti–floating anchor bolt in the basement with the main building is designed according to the conventional layout method, and the contribution of the stiffness of the main building and basement to the internal force of the anchor bolt cannot be considered. The actual stress of the evenly arranged anchor bolt is uneven, and the actual bearing capacity of the anchor bolt may be greater than that designed according to the current common method. The stiffness of the main floor and the basement of the main basement varies greatly. The FEM is used to carry out anti–floating integral calculation and analysis. It is found that the design of the variable stiffness method for anti–floating design can make the force of the anchor and the bottom plate reach the best.
