某钢筋混凝土框架-钢支撑结构设计

Structure design of a reinforced concrete frame-steel bracing

新浪总部办公楼采用钢筋混凝土框架-钢支撑结构体系,结合建筑立面形态和平面布局,部分框架柱采用了斜柱,其中中庭开洞周边存在部分单跨框架,平面超长外围尺寸199.2m×91.2m。介绍了该项目的结构布置、方案选型、技术难点和超限情况,并提出了一系列的结构设计措施。分析结果表明,结构能够达到预期的设计目标。

The structure of Sina headquarters office building is reinforced concrete frame and steel bracing system.In combination with the facade form and the plane layout of the building,some of the frame columns are inclined columns.There are some single span frames around the opening of the atrium.The outer size of the plane is overlength 199.2 m×91.2 m.The structure layout,scheme selection,technical difficulties and overlimit situations were introduced.In the meantime,a series of structure design solutions were proposed.The analysis results show that the structure can achieve the desired design goals.
