| 摘 要： | 北京中关村金融中心连廊工程平面及立面均为弧形,支承在不同的结构主体上,体型独特,支承条件复杂。主体采用大跨度空间钢桁架结构体系,屋面采用异型空间刚架结构体系。在施工阶段,主桁架支座设计成纵向可自由滑动的滑动铰支座,以释放部分内力。采用抗震球形钢支座消除相对位移对各独立主体结构产生的影响。由于屋面风荷载效应显著,通过风洞试验确定连廊屋面的风压分布情况。

| Abstract: | The spatial gallery of Zhongguancun Financial Center of Beijing is very special for the planar and the supporting conditions are very complicated.Large span steel spatial truss system is adopted for the floor structure and allotype gabled frames are adopted for the roof structure.In order to partial release the internal forces,the bearing of the main trusses are designed as free sliding bearings in construction stage.Special bearing devices are adopted to overcome differential displacements between independent buildings.As the response of the structure under wind loads is significant,the distribution of wind pressure on the roof is determined by wind tunnel test. |
