钢柱柱脚为上部钢结构与基础底座连接的重要枢纽,影响着整个上层结构的刚度和强度。但世界各国目前所采用的计算柱脚锚栓的方法很不统一,计算结果差异很大。在所采用的方法中,一般都缺少必要的说明和分析,试验验证更少见到。在各种计算方法中,经常采用不同的混凝土压应力分布曲线图形(三角形、长方形或抛物线形)。当认为靴梁刚度为无穷大,采用温盖尔理论时(图1(a)),在弹性阶段有的采用三角形图 The post of steel column is an important hinge connecting the upper steel structure and the foundation, which affects the stiffness and strength of the entire upper structure. However, the method used to calculate the anchorage bolts currently used by various countries in the world is not uniform, and the calculation results are quite different. In the methods used, the necessary explanations and analysis are generally lacking and the test verification is less visible. In various calculation methods, different concrete stress distribution curve patterns (triangular, rectangular, or parabolic) are often used. When the stiffness of the shoe beam is assumed to be infinity, when using the Wingler theory (Fig. 1(a)), some triangles are used during the elastic phase.
