In this study, the concrete cone capacity, concrete cone angle, and load–displacement response of cast-in headed anchors in geopolymer concrete are explored using numerical analyses. The concrete damaged plasticity (CDP) model in ABAQUS is used to simulate the behavior of concrete substrates. The tensile behavior of anchors in geopolymer concrete is compared with that in normal concrete as well as that predicted by the linear fracture mechanics (LFM) and concrete capacity design (CCD) models. The results show that the capacity of the anchors in geopolymer concrete is 30%–40% lower than that in normal concrete. The results also indicate that the CCD model overestimates the capacity of the anchors in geopolymer concrete, whereas the LFM model provides a much more conservative prediction. The extent of the difference between the predictions by the numerical analysis and those of the above prediction models depends on the effective embedment depth of the anchor and the anchor head size. The influence of concrete surface cracking on the capacity of the anchor is shown to depend on the location of the crack and the effective embedment depth. The influence of the anchor head profile on the tensile capacity of the anchors is found to be insignificant.

在本研究中，通过数值分析探讨了地质聚合物混凝土中埋入式带头锚杆的混凝土锥体承载力、混凝土锥角和荷载-位移响应。ABAQUS 中的混​​凝土损伤塑性 (CDP) 模型用于模拟混凝土基材的行为。将地聚合物混凝土中锚杆的拉伸行为与普通混凝土中的拉伸行为以及线性断裂力学（LFM）和混凝土能力设计（CCD）模型预测的拉伸行为进行了比较。结果表明，地质聚合物混凝土中的锚杆承载力比普通混凝土中的锚杆承载力低30%~40%。结果还表明，CCD 模型高估了地质聚合物混凝土中锚杆的能力，而 LFM 模型提供了更为保守的预测。数值分析的预测结果与上述预测模型的预测结果之间的差异程度取决于锚杆的有效埋入深度和锚头尺寸。混凝土表面裂缝对锚栓性能的影响取决于裂缝的位置和有效埋深。发现锚头轮廓对锚的抗拉能力的影响是微不足道的。
