| 摘 要： | 本文着重研究两跨或三跨连续梁在不同跨度比、不同静活荷载比以及各种支座和跨中刚度比值下支座弯矩的变化规律，采用与弹性分析值进行比较的方法，提出钢筋混凝土连续梁考虑内力重分布后支座弯矩的修正系数，以求使用阶段连续梁的内力及位移计算更切实际。

| Abstract: | This paper emphasizes the study of variation laws of support moments of two-span or three span continuous beams under various span ratios, various dead to live load ratios, and various support point beam stiffness to midspan stiffness ratios. On the basis of comparison with results of elastic analy sis, coefficients of correction of support moments of reinforced concrete contiuous beams have been put forward taking into account the redistribution of internal forces, so that the calculation of internal forcesof continuous beams under service loading becomes more realistic. |
