This paper discusses the comparative study of design moments for pile cap with conventional methods and finite element analysis. If a detailed finite element analysis is adopted, flexibility of the pile cap is considered. When a pile cap is designed by truss analogy, 80% of the tension reinforcement is concentrated in the region where the cap is supported on piles and at the column, which depends on design moments. It is observed that the difference in the design moments was considerable and should be taken into account for calculation and placing of reinforcement.

桩帽设计力矩的比较

本文讨论了传统方法与有限元分析对桩帽设计弯矩的比较研究。如果采用详细的有限元分析，则考虑桩帽的柔韧性。当通过桁架类比设计桩帽时，取决于设计力矩，将80％的抗拉钢筋集中在桩帽支撑在桩上和柱子上的区域中。可以看出，设计弯矩的差异很大，在计算和布置钢筋时应考虑到这些差异。
