基于ANSYS的混凝土收缩徐变效应分析

综述了采用ANSYS进行混凝土徐变收缩分析的方法,以线形叠加原理为理论基础,提出了可以考虑施工过程的ANSYS混凝土徐变收缩的计算方法;以软件材料库中所提供金属蠕变的本构关系曲线分段拟合常应力作用下的混凝土徐变曲线,结合离散化模型的有限元模型处理方法,利用APDL进行二次开发,计算了某特大桥节段施工的收缩徐变效应,验证了方法的正确性。

The concrete shrinkage and creep effect analysis based on ANSYS

The concrete creep and shrinkage analysis methods with ANSYS were generalized,with linear superposition as theoretical basis,the ANSYS concrete creep and shrinkage calculation methods considered construction process were proposed,the silicon creep curve in common stress effect was fitted segmented with metal creep constitutive relation curve provided from software material storage,combined with the finite element model treating method of discretization model,using APDL secondary development,a super large br...
