预应力方法广泛地应用于工程结构中 ,其中锚具起着重要作用。预应力的效果取决于锚具所能承受的荷载。然而 ,锚具内部的力学性能并不能通过实验来分析。本文采用有限元方法给出了单孔锚具的弹塑性分析结果 ,分析了摩擦系数对锚具性能的影响。计算结果表明 :在可测试的区域内 ,计算数值与实验结果一致。 Prestressed methods are widely used in engineering structures, of which anchors play an important role. The effect of prestress depends on the load the anchor can withstand. However, the internal mechanical properties of anchors can not be analyzed experimentally. In this paper, the results of elasto-plastic analysis of single-hole anchors are given by finite element method, and the influence of friction coefficient on the performance of anchors is analyzed. The calculation results show that the calculated values ​​agree well with the experimental results in the testable area.
