| 摘 要： | 应用结构力学和混凝土结构的理论,分析了具有弹性支点的两跨连续梁的内力,并提出了采用弹性支承加固简支梁时的最佳刚度的概念.通过分析得出了被加固梁最佳支承刚度的计算方法,以及与其对应的最大承载力的计算方法.实例计算分析给出了不同K值时两跨连续梁承载力的变化曲线,并说明当选择最佳支承刚度时,可使被加固梁的承载力最大.

| Abstract: | The internal force of continuous beam with elastic middle support is analyzed through the theories of structural mechanics and concrete structure;and a new concept of the optimum support rigidity is proposed when applying the elastic support to reinforce the simply supported beam.This paper gives a method of calculating the optimum support rigidity of the reinforced beam and calculating the corresponding greatest bearing capacity.This paper also gets the varied curve of continuous beam's bearing capacity in a series of value K,and illustrates that,when choosing the optimum support rigidity,the bearing capacity of reinforcecd beam will be the greatest. |

| Keywords: | reinforced beam support rigidity greatest bearing capacity |
