高层建筑桩基承台按应力图形配筋的设计方法

THE DESIGN OF PILE CAPS OF HIGH-RISING BUILDING

针对高层建筑桩基承台一般设计方法存在的问题 ,提出了用有限元法对结构整体进行分析 ,并按承台的应力图形配筋的设计方法。把此方法应用于武汉香格里拉大酒店塔楼的承台板设计计算 ,说明了这一方法的合理性和实用性。

A method to design the pile caps of high?rising building is proposed in the paper The behavior of pile caps is complicated;the pile,soil,and super?structure are situated in a space stress state The finite element method is suited to analyze the whole structure,and the reinforcements in pile cap are placed in accordance with the computed stress diagrams Some shortcomings accompanies with the current design method of the pile caps are averted A project of the pile caps of the Shangri?La hotel is designed by the proposed method;it is shown that the proposed method is feasible and practical
