摘要
以等截面梁内力变形通用方程为基础,采用有限元划分单元的思想,使用矩阵递推公式化简得出了求解两端任意支承、中间有若干铰支座和中铰的静定超静定阶梯变截面梁的约束反力及内力变形的通用方程.并使用实例验证了该方程.该方程的形式规则统一,计算过程简单,稍加改进可以推广到平面刚架的内力和变形计算中去.
Based with the general equation of calculating inner force and deformation of uniformed-section beam and principle of limited element and matrix recursion,the general equation of calculating inner force and deformation of non-uniformed section beam with arbitrary constraint is reduced in this paper.An example is given to verify the equation.The equation is simple,uniform and easy to extend to plane rigid frame with some modification.
