【摘要】：三门峡文体中心会展中心采用现浇钢筋混凝土框架-剪力墙结构体系。会展中心设计为一个完整的结构单元,不设永久缝,通过控制施工顺序、调整混凝土要求、合理分配伸缩单元等措施,结合整套施工工艺和方法,解决了抗震性能、混凝土裂缝控制难题;对于大空间、大跨度屋面,采用相贯线管桁架或与相贯线管桁架结合的张弦钢结构,以三管受压钢管桁架和受拉的钢索共同组成管桁架+预应力张拉索结构体系;2层展厅地面采用27m双向大跨桁架,设计时在保证2层无柱展厅布展荷载使用的同时,最大限度地减少1层展厅结构柱的数量,确保上下两层均达到展厅的使用要求和投资控制。结构设计采用了多项先进技术和分析程序,很好地解决了建筑功能和空间复杂、平面超长、跨度大等多项难题。
[Abstract]:The exhibition center of Sanmenxia Sports Center adopts cast-in-place reinforced concrete frame-shear wall structure system.The convention and exhibition center is designed as a complete structural unit with no permanent joints. By controlling the construction sequence, adjusting the concrete requirements, reasonably distributing the expansion units and other measures, combined with the whole construction technology and method, the aseismic performance is solved.For large space and long span roof, the intersecting line pipe truss or Zhang Xian steel structure combined with intersecting line pipe truss is used.The prestressed tensioning cable structure system of the pipe truss is composed of three tube compressed steel tube truss and the steel cable under tension. The floor of the exhibition hall on the 2nd floor adopts 27m bidirectional large-span truss. When designing, the load distribution of the two-story exhibition hall without columns is guaranteed.Minimize the number of structure columns on the first floor of the exhibition hall to ensure that the upper and lower floors meet the requirements for the use of the exhibition hall and investment control.Many advanced techniques and analysis programs are adopted in the structural design, which solve many problems such as complex building function and space, super-long plane, long span and so on.
