| 摘 要： | 混凝土徐变对结构应力、变形的影响较大,进行准确的结构分析必须考虑混凝土徐变。按龄期调整的方法对混凝土徐变计算有效模量理论进行修正,提出等效弹性模量计算公式。运用大型通用有限元软件ANSYS参数化程序设计语言APDL编写命令,在每一时段赋予材料对应等效弹性模量并计算混凝土结构的徐变,把徐变问题化为相当的弹性问题。并通过算例验证此方法在实际工程应用中的有效性。

| Abstract: | Concrete creep has an impact on the stress and deformation of the structure deeply.Therefore,the concrete creep should be considered in the more accurate analysis of structure.The Method of Effective Modulus to calculate concrete creep is amended by the means of adjusting concrete age and the formula to calculate the equivalent modulus is come up with.Use APDL of ANSYS to compile lines and endow the material with the equivalent modulus to calculate concrete creep.The calculation of concrete creep is transfo... |
