大连国际会议中心是复杂空间组合结构,外围护结构不但要将整个复杂曲面建筑物外部围合,而且还要将悬挑屋盖、钢平台有机连接起来。根据建筑立面设计要求,外围护结构的形式为曲面框架。该曲面框架少部分落地、大部分悬挂。根据整体计算的结果,在地震、风和温度作用下,外围护框架承担了相当可观的竖向和水平荷载,有效地保证组合结构整体性。外围护框架外部悬挂大量为建筑造型而设置的羽翅构造,风荷载的作用非常明显。外围护框架上镶填大量玻璃幕墙,框架空间变位的控制影响到玻璃幕墙的安全使用。
Dalian International Convention Center is a complex combination of space structure, the external envelope not only to surround the entire complex surface buildings outside, but also cantilevered roof, steel platform organically connected. According to the design requirements of the building facades, the form of the external envelope is the curved frame. The surface of the framework of a small part of the landing, most of the suspension. According to the overall calculation results, under the action of earthquakes, winds and temperatures, the outer protective frame takes considerable vertical and horizontal loads, effectively ensuring the integrity of the composite structure. Outside the framework of the external support for a large number of architectural shapes and the formation of the feather wing structure, the role of wind load is very obvious. A large number of glass curtain walls are set on the outer support frame, and the control of the displacement of the frame space affects the safe use of the glass curtain wall.
