摘　　要：分析某小学项目结构设计方案,提出“先放后抗”大跨度转换结构设计理念。通过合理修改结构模型的施工模拟计算次序,采用与计算方案相配套的施工工艺流程,调节并增加转换层下部结构在整体自重荷载下的分担比例,从而有效降低了上部结构的次生内力。现场实测数据与理论分析结果接近,且变形规律类似。说明该理念能有效降低此类结构的设计难度,为类似项目参考运用提供依据。This paper analyses the structural design scheme of a primary school,and puts forward the concept of“Release before Resist”for designing large-span transfer structure.By appropriately modifying the simulated construction sequence of the calculation model and conducting the construction technology and process correspond to the model,the weight share ratio of structure below the structural transfer floor was increased,and therefore effectively reduced the secondary internal force of the upper structure.The data measured on site was close to the theoretical analysis results,their deformation patterns was similar.It shows that the concept can effectively reduce the difficulty of structural design in large-span transfer structure,and provide reference for other similar projects.
