摘　　要：建筑结构设计中,框架梁一般有左端、跨中、右端3个控制截面,每个控制截面上对应抗震情况下的荷载效应组合和非抗震情况下的荷载效应组合两种工况,荷载效应组合选取的正确与否直接关系着建筑结构的使用安全。对现行的《建筑结构可靠性设计统一标准》《建筑抗震设计规范》及《建筑与市政工程抗震通用规范》相关内容进行分析,得出框架梁不同截面位置起控制作用的荷载效应组合。In the design of building structure,generally the frame beam has three control sections:the left end,the middle span and the right end.Each control section corresponds to two working conditions:the combination of load effect under seismic conditions and the combination of load effect under non-seismic conditions.The correct selection of the combination of load effect is directly related to the safety of building structure.Based on the analysis of the current“Unified Standard for Reliability Design of Building Structures”“Code for Seismic Design of Buildings”and“General Code for Seismic Design of Buildings and Municipal Engineering”,the study obtains the load effect combination of different section positions of frame beams.
