| 摘 要： | 针对解析算法的缺点,建立适合于任意截面钢筋混凝土构件的正截面承载力计算方法.引入计算截面性质常用的节线法,将混凝土构件正截面承载力解析算法列式中的相关项改为受压区高度的隐式函数,使表达式形式与截面形状无关,避免了列式对截面形状的依赖,最后通过数值方法求解非线性方程.数值算法计算流程简洁,简化了由于截面形式限制造成的复杂流程,适合程序实现,计算结果更为精确.

| Abstract: | Aiming at the defects of analytical algorithm,this paper presents a numerical algorithm fitting for any section shape of concrete member for strength capacity calculation.The numerical algorithm based on division lines method which is originally used in calculating section geometry properties.With this method,the internal force equations are expressed with implicit functions and can be resolved with numerical algorithms.The implicit internal force equations,in which expressed format is independent of sectio... |
