摘　　要：随着现代建筑向复杂方向发展,竖向构件会出现不连续的情形,这会使竖向荷载的传递方式更加多样化。为此,通过对竖向荷载类型及特点进行归纳总结,将竖向荷载传递路径分为三类,包括竖直向下传递,竖向荷载通过转换梁、转换桁架、转换斜撑和转换拉索等转换结构沿水平方向传递至相邻竖向构件再向下传递,以及竖向荷载通过吊杆以屋顶悬挂或分区悬挂的方式向上传递,再通过水平转换结构传递至其他竖向构件,最后向下传递至基础。传递路径与建筑造型和建筑功能密切相关,通过大量工程实例,对复杂建筑结构竖向荷载传递路径的选取依据和工程实践的总结,得到了竖向荷载两类传递的结构适用跨度与范围,以期为复杂建筑结构竖向传力体系的设计提供参考。With the development of modern architectures,vertical components in some cases are discontinuous,which makes the transition paths of vertical loads more diverse.For this reason,this paper first briefly summarizes the types and characteristics of vertical loads,categorizing the transition paths of vertical loads into three types,including direct vertical downward path,vertical loads transferring in the horizontal direction through transition beams,transition trusses,transition bracing,transition tendons and other transition structures to adjacent vertical components,and vertical loads transferring upwards through tension rods by means of roof suspension or regional suspension,then transferring in the horizontal direction to other vertical components,ultimately transferring downwards to the foundation.The transition paths are highly dependent of architectural shape and function,and the selection basis and engineering practices of vertical load transition paths are generalized through analysis of various engineering cases,in order to obtain the application spans and scopes of transition structures for the last two types of vertical transition paths,which can be used in the design of vertical load transition paths in complex buildings as reference.
