正交各向异性钢筋混凝土板结构弹性常数的确定

Confirm of elasticity cofficient about or thotropic plates of reinforced-concrete

从以往的混凝土结构强度计算和截面设计理论出发,根据复合材料的细观力学性能和以往的试验结果,对复合材料的弹性常数进行了分析研究,推导出了钢筋混凝土板结构的弹性常数预测值,从而为以后运用正交各向异性的弹性力学的性质进行钢筋混凝土板结构计算提供了重要的理论依据,弥补了极限状态设计中只考虑混凝土的弹性常数的不足,克服了目前结构有限元计算中由于工程结构本身的复杂性致使钢筋单元难以输入的缺点,同时,为其他钢筋混凝土结构的概念设计提供了思路。

Beginning with the theory of concrete intensity and section design, According to meso - mechanics of composite materials and previous test results, elasticity cofl＇icient of composite materials are researched, and prediction value of plate about reinforced concrete is given, and so important theory basis of calculating reinforced concrete plate is provided using or thotropic elastic mechanics. The deficiency of limit state design is made up; due to complexity of engineering structure perse, the shortage is conquered in structure finite computation presently. Moreover, thoughtway of concept - design about other reinforced concrete structure is offered.
