沉降差作用应参加效应组合及防范措施

Effect of the settlement difference should be added to the effects combination and the preventive measures

针对基础不均匀沉降对结构内力的影响,分别在重力荷载、风荷载及相邻桩基的允许沉降差作用下进行了框架弯矩的内力分析及对照比较,从设计、施工、使用等方面提出了减少沉降差引起内力的措施。

According to the influence of the uneven settlement of the foundation to the structural internal force, the author carries out the internal force analysis Of the moment of the frame and the comparison under the effect of the gravity load, the wind load and the allowable settlement difference of the adjacent pile foundation, puts forward the measures to reduce the internal force caused by the settlement difference from the design, the construction and the use.
