[摘要] 上海张江中区B-3-6地块研发楼平面较为复杂，由钢结构中庭及环绕其周围的五个混凝土主楼组成，平面布置像一个手掌。采用了弹性球型钢支座、约束屈曲型支撑等新技术。中庭钢结构对风荷载比较敏感，且体型复杂，进行了风洞试验确定风压系数。

Abstract: The construction plane of Shanghai Zhangjiang Central District B-3-6 R&D building block is complicated, which surrounded by a steel structure around the atrium and the five main components of concrete, like a hand layout. Steel ball bearings with a flexible, constraint-based support for new technologies such as buckling were adopted. Atrium steel sensitive to wind loads and the size is complex. Wind tunnel test was carried out to determine pressure coefficients.
Keywords: flexible steel ball bearings; constrained buckling type support; wind tunnel test
