六桩厚承台的传力模式分析

Analyse on Load Transfer Model of Thick Pile Caps with Six Piles

通过对2个不同配筋形式的钢筋混凝土六桩厚承台受冲切的试验,探讨了钢筋混凝土六桩厚承台的破坏模式和受力机理。结果表明,钢筋混凝土六桩厚承台的传力机理不同于一般受弯构件,建议分析其受力时采用拉压杆模型。

This paper discusses the failure mode and the load transfer mechanism of Steel Reinforced Concrete thick pile caps with six piles based on the test of punching shear of two reinforced concrete pile caps with differently arranged reinforcements of six piles.The results of the test point out that the model load transferring of six thick pile caps is different from the ordinary curve members,suggest that we apply the model of Strut-and-Tie theory when we analyse its load transferring.
