Method and system for accurately calculating bearing capacity of double-pipe concrete column
The invention discloses a method and system for accurately calculating the bearing capacity of a double-pipe concrete column, and the method comprises the following steps: obtaining calculation parameters of the double-pipe concrete column, and building the stress and deformation relation between all parts of the double-pipe concrete column; the extrusion stress between all the parts of the double-pipe concrete column is solved, and the bearing capacity is solved according to the calculation parameters and the solving result; according to the method, the stress and deformation of each component of the double-pipe concrete column in an elastic-plastic stage are analyzed, a calculation method for the bearing capacity of a test piece is given by establishing a deformation coordination equation, the radial extrusion stress between the components is solved, the load borne by each component is further solved, and the stress of the test piece is calculated. The method can more truly and effectively reflect the influence on the bearing capacity calculation result due to the fact that each component of the material cannot reach respective peak stress at the same time, the result is more objective and accurate, and the method is of great significance for predicting the bearing capacity of test pieces made of materials with different strengths.
本发明公开一种精确计算双管混凝土柱承载力的方法及系统，其方法包括以下步骤：获取双管混凝土柱的计算用参数，建立双管混凝土柱各部分之间受力和变形关系，求解双管混凝土柱各部分之间的挤压应力以及根据计算用参数和求解结果求解承载力；本发明对双管混凝土柱的各组成部分在弹塑性阶段的受力和变形进行分析，并通过建立变形协调方程，给出试件承载力的计算方法，求解得到各组成部分之间径向挤压应力，进而求得各组成部分承担的荷载，可以更加真实有效地反映材料各组成部分无法同时达到各自峰值应力对于承载力计算结果造成的影响，结果更为客观和准确，对于预测不同强度材料制作的试件的承载力意义重大。
