本文导出弹性支承连续梁各跨度的内力及形变递推计算公式,据以编制程序,用微型计算机计算。本程序对于解算变截面杆件的连续梁及绘制内力图特别方便;除用于静力计算外,还可推广应用于连续梁的动力计算。对于弹性地基梁来说,也可离散为若干跨弹性支承梁计算。对于一根具有不同弯曲刚度、基床系数的弹性地基梁,用本法计算,远较其他解析法,如微分方程法或Light-foot的弯矩分配法等直接便利得多。
In this paper, the internal forces and deformation recursive calculation formulae for each span of elastically-supported continuous beams are derived. According to this program, the calculations are performed using a microcomputer. This procedure is particularly convenient for solving continuous beams with variable cross-sections and drawing internal force diagrams. Except for static calculations, it can also be applied to the dynamic calculation of continuous beams. For the elastic foundation beam, it can also be discretely calculated for several span elastic support beams. For an elastic foundation beam with different bending stiffness and bed coefficient, using this method is much more convenient than other analytical methods such as differential equation method or Light-foot bending moment distribution method.
