摘要
随着大跨度混凝土结构的广泛应用,随之产生的下挠变形问题也成为影响施工质量的关键因素.从实际出发,针对青岛市地铁指挥中心工程进行挠度现场实测,并结合有限元软件Abaqus进行建模分析,总结出了大跨度混凝土水平结构在不同施工阶段下,下挠变形的变形规律及特征.
With the increasing usage of long span concrete structure,the deflection of horizontal elements come to be a major factor of affecting the quality of construction.Based on practical engineering in Qingdao,deflection of structures in construction is measured.In combination with the finite element software Abaqus simulation,disciplines and characteristics of deflection of long span concrete structures＇ horizontal elements are analyzed in the paper.
