本文通过非线性数值分析对钢筋混凝土 (RC) 桩支撑基础的剪切破坏机制进行了评估。刚体弹簧模型是离散型方法之一，用于分析 RC 基础的剪切破坏行为。该数值模型预测了三维裂纹的发展和冲切剪切能力，并通过与实验观察结果的比较进行了验证。进行敏感性分析来研究纵向钢筋布置对施工中钢筋布置生产率的影响。
This paper presents an evaluation of shear failure mechanisms in reinforced concrete (RC) pile supported footings by using a nonlinear numerical analysis. A rigid-body-spring model, which is one of discrete type approaches, is used to analyze shear failure behaviors of RC footings. The numerical model predicts the three dimensional crack development and the punching shear capacity, and is validated by comparison with experimental observations. Sensitivity analyses are conducted to study the effect of longitudinal reinforcement arrangement that affects productivity of reinforcement placement in construction.
