摘　　要：对贵阳市某大楼型钢混凝土桁架转换层进行了施工期间的监控，并利用有限元分析软件ANSYS建立了带有型钢混凝土桁架转换层的结构有限元分析模型。针对工程中连接、构造和施工影响等相关因素进行有限元模型的对比分析，明确各因素对桁架受力的影响。结合施工阶段的监控数据，分析此工程中桁架受力状态的成因，为准确判断工程在正常投入使用后的受力变形情况奠定基础。The construction monitoring to the steel reinforced concrete truss transfer storey of a certain building in Guiyang is carried on,and the finite element analysis model of the structure with steel reinforced concrete （SRC） transition truss by finite element analysis software ANSYS is established. Contrastive analysis of the finite element model for the factors of connection, composition,construction impact and so on is made,and the influence of these factors on the truss is confirmed. Combined with monitoring data during construction phase, the cause of the truss stress state is analyzed, and the foundation to accurately judge the situation of the project in service stage is laid.
