摘要
计算拱轴系数是拱桥设计的重要组成部分。本文以有限元方法为基础 ,从数值分析角度 ,建立拱轴系数与拱内弯矩关系式 ,并采用线性规划方法计算最优拱轴系数。针对上述算法 ,在FortranPowerStation 4 .
Calculation of the arch-axis coefficient is important in arch bridge design. In this paper, a connection formula between coefficient of arch axis and arch bending moment is established basing on finite element method and numerical value analysis, and linear programming method is used to calculate the best coefficient of arch axis. Aiming at the method mentioned above, a corresponding calculation software is developed in Fortran PowerStation 4.0.
