| 摘 要： | 目的为建立适合于任意截面的正截面承载力计算方法,将原有的解析算法改为数值算法.方法根据数值计算的特点,引入桥梁电算中计算截面性质惯用的截线法,提出了混凝土构件正截面承载力的数值算法.结果数值算法在正截面承载力计算列式中,混凝土截面几何性质项表达为受压区高度的隐式函数,使得表达式与截面形式无关.结论与解析算法比较,数值算法计算流程简洁,适合程序实现,计算结果更为精确.

| Abstract: | In order to set a strength capacity calculation method suitable to any section,analytical algorithm derived from classical teaching materials has been changed for numerical algorithm.Based on the characteristics of numerical calculation,division lines method is introduced,which is usually used in bridge-electronic computation to calculate section geometry properties,and numerical algorithm on strength capacity calculation of concrete member is put forward.In the numerical algorithm,calculation formulas are expressed in implicit function,with which calculation is uncorrelated with member section shape.The corresponding programs are expressed with UML model to testify the accuracy and practice of algorithm presented.The numerical algorithm is suitable to any shape of member sections in strength capacity calculation. |
