摘要
根据笔者提出的方法,同时考虑弯曲、剪切和轴向变形,导出了抛物线拱元传递矩阵的解析公式,建立了多孔连拱传递矩阵方程.仅用≤7×7阶矩阵运算,即可求得连拱荷载效应的精确解答.
According to the method developed by the author,and by considering bending, shearing and axial deformations, the transfer matrix’s analytic formulas of the parabolic arch element and the transfer matrix equations of the multi arch are derived. Only by using the matrix operation less than or equal to 7×7 rank, the load effects in multi arch can be analyzed.
