| 摘 要： | 由于连续梁具有弹性支座，在荷载作用下产生了支座沉降。连续粱的支座反力和内力将出现变化。计算了两跨连续梁所出现的反力与内力的重分配问题。并结合钢筋混凝壬连续梁的承载力试验，证实了得到的结果与理论值能较好吻合。同时针对不同支承刚度系数值的范围，提出了一些设计建议。

| Abstract: | Some changes will happen in the support reacting force and internal force of continuous beam with elastic support when the support subsides under the loading function. This paper calculates the redistribution of the reacting and internal force of continuous beam when the middle support is elastic, and verifies the calculation result and testing value can be well identical, through the bearing capacity tests of reinforced concrete continuous beam. At the same time this paper proposes some design suggestions in dealing with the coefficient value range of support rigidity. |
