摘要
本文介绍15个钢纤维混凝土四桩厚承台足尺试件的试验结果及三维非线性有限元分析情况,分析影响纲纤维混凝土四桩厚承台受冲切承载力的主要因素,提出了受冲切承载力计算公式。研究表明,纲纤维的掺入可有效地改善桩承台的受冲切性能,提高桩承台的受冲切承载力,减小承台的有效厚度。
This paper introduces the test resultS of 15 full-scale specimens and 3D nonlinear finite element analysis of punching shear of steel fiber reinforced concrete thick caps with four piles. The main factors affecting the punching shear bearing capacity of the thick cap are studied and the formula for calculating the beating capacity is presented. The study shows that adding steel fiber into concretecan improve effectively the punching shear bearing capacity of pile cap, or else the effective depth of the pile can be reduced.
