摘　　要：以贵阳市双龙经济技术开发区某7层混凝土框架结构为工程背景,基于MIDAS/Gen软件,采用按龄期调整的有效弹性模量法计算混凝土收缩徐变对结构的影响,分析了收缩徐变对柱竖向收缩、楼板应力、层间位移等因素的影响。Taking a 7-storey concrete frame structure in Shuanglong economic and technologic development zone of Guiyang as the engineering background,based on MIDAS/Gen,the age-adjusted effective modulus method was adopted to calculate the concrete shrinkage and creep effect on the structure,and the influence of shrinkage and creep on column vertical shrinkage,floor stress and displacement between layers were analyzed.
