In this study, an ordinary state-based peridynamics (OSBPD) modeling method is proposed to simulate the 3D problem of anchor bolt pullout in concrete. The peridynamic methodology is employed as an analytical instrument to circumvent the challenges encountered within the finite element method. A bilinear cohesive constitutive model is employed to describe the plastic behavior of plain concrete. This modeling method is used in two cases. One is the elastic deformation of bi-material cantilever beam, and the other is the failure of anchor bolt pullout in concrete. The effect of concrete thickness and embedment depth of anchor bolt are investigated by several groups of simulation. The progressive failure process of the anchor bolt pullout test is also presented in detail. By comparing with existing research, this modeling method without additional failure criteria can accurately predict the peak pullout load and the propagation of 3D multi-cracks.

一种模拟混凝土中锚栓拔出的普通基于状态的近场动力学建模方法


在这项研究中，提出了一种普通的基于状态的近场动力学（OSBPD）建模方法来模拟混凝土中锚栓拔出的3D问题。采用近场动力学方法作为分析仪器来规避有限元方法中遇到的挑战。采用双线性内聚本构模型来描述素混凝土的塑性行为。该建模方法用于两种情况。一是双材料悬臂梁的弹性变形，二是混凝土中锚栓拉拔破坏。通过多组模拟研究了混凝土厚度和锚杆埋深的影响。还详细介绍了锚栓拉拔试验的渐进破坏过程。通过与现有研究进行比较，该建模方法无需额外的失效准则即可准确预测峰值拉拔载荷和3D多重裂纹的扩展。
