四桩承台冲切承载力分析(英文)

The Analysis for Punching Shear Bearing Capacity of Pile-caps Supported on Four Piles

结合试验资料,以桩基承台空间桁架传力机理和破坏模型为基础,推导了钢筋混凝土四桩承台混凝土斜压杆承载力计算公式,本文公式值与试验结果吻合的程度比规程公式好.

Base on load transmission mechanism of space truss and broken model for thick pile-caps, and by the analysis of test materials, a formula for calculating the bearing capacity of concrete compression strut and the design method of space truss of pile cap supported on piles is presented. Predictions by the proposed method are compared with experimental results and other established calculation methods. Generally, the calculated results coincide precisely with the practical measurements.
