| 摘 要： | 定量分析了用强度等级相同的轻骨料混凝土替代普通混凝土后,在承载力保持不变,同时挠度也满足规范要求的前提下,不同跨径的矩形截面简支梁在钢材用量、混凝土用量、跨中挠度等方面的变化情况.计算结果表明,轻骨料混凝土应用于大跨梁结构具有明显的经济效益.

| Abstract: | In this paper,the author analyse quantity variation that the different span rectangle section simple supported beam demand quantity of steel,concrete and its variation of mid-deflection in the lightweight aggregate concrete insteading of the same strength standard ordinary concrete, meanwhile,keeping constantly bearing limit load and according with deflection standard.The result show that lightweight aggregate concrete to be in large span beam structure has the obvious technical and ecnomic effects. |
