【摘要】 通过对3个钢筋混凝土双柱六桩厚承台的试验和有限元计算分析,揭示其传力机理和破坏模式,进而讨论不同配筋形式对六桩厚承台极限承载力的影响,证实六桩厚承台的传力路径更类似于空间拉杆拱模型。更多还原

【Abstract】 Based on the experimental investigations of three thick six-pile cap specimens and finite element computations,the load-transferred mechanism and the failure modes are analyzed,and the effect of different steel bar arrangements on the ultimate bearing capacity of thick six-pile caps are thus discussed.The results show that the load-transferred path of thick six-pile cap is well correlated with the three-dimensional arch-and-tie model.更多还原
