预应力混凝土收缩徐变空间计算程序

Spatial calculation program of prestressed concrete shrinkage and creep

针对目前桥梁结构非线性分析软件的不足,按有效弹性模量的计算方法,编制了用于分析预应力混凝土桥梁结构收缩、徐变的程序,并根据工程实例,验证了程序的合理性与实用性,以促进其推广。

In view of the shortcomings of nonlinear analysis software of bridge structure at present,according to the calculation methods of effective elastic modulus,the paper formulates the program for analyzing the shrinkage and creep of prestressed concrete bridge structure.According to the engineering examples,it testifies the rationality and applicability of the program,so as to promote its promotion.
