大连国际会议中心结构设计研究综述

大连国际会议中心工程以16个内藏钢桁架的钢筋混凝土交通筒体构成整个建筑物的竖向承重和水平抗侧力结构。在标高15.3m处支撑起钢桁架构成主要使用功能钢平台,建筑中部设置1 700座歌剧院,在钢平台外边缘悬挑部位有7个500人以上会议厅。13个交通筒上部设置15个屋盖支撑点,形成不规则大跨悬挑屋盖。曲面外围护框架结构与屋盖、悬挑钢平台相连,构成空间组合结构,共同抵御地震、温度和风荷载作用。采用性能化设计方法和目标,并提出相应计算方案、设计原则、试验要求,保证整体设计的有序和有效性。

Structural design and research on Dalian International Conference Center

The vertical load and horizontal lateral are resisted by 16 concealed steel frame reinforced concrete traffic cores in Dalian International Conference Center.The steel platform for major functions supported with steel truss is built in the elevation of 15.3m.The central building is a opera with 1700 seats,and 7 meeting halls with more than 500 seats are built on the edge of steel platform.Fifteen roof support points are arranged at the upper part of the 13 traffic cores,which leads to an irregular large cantilevered roof.Curved frame structure is connected with the roof and cantilever parts of steel platform,all of them form the spatial structure to resist the earthquake,temperature and wind loads.Performance-based design method and target were used for structural design.The corresponding calculation program,design principles and test requirements were put forward to ensure the validity of the overall design.
