佛山雄盛王府空中连廊钢结构支座研究和设计

Research and Design of Steel Skybridge Bearing for Xiongshengwangfu in Foshan

佛山雄盛王府工程由于建筑功能需要,在结构的2～5层设置钢结构连廊。该结构设计巧妙地在3层位置的柱子顶部采用竖向释放的连接构造,将4层的连廊折分成上下2个2层的连廊,有效地化解了单层支座反力过大的问题。为了减轻两侧塔楼地震作用下的摆动对连廊的不利影响,连廊每层设置了4个摩擦摆支座。摩擦摆支座可以有效地减少地震力的输入,并具有复位的功能,地震后连廊可无需修复自动归位。

In the design of Xiongshengwangfu project,a skybridge was set up on floor 3 to floor5 in order to meet the function demand of the building. Vertical degree of freedoms in tops of columns on the floor 3 were released to divided a 4-floor skybridge into two 2-floor sky- bridges,which is the special point of the skybridge design. By this way,the support reactions were reduced availably. In other hands,4 friction pendulum bearings were installed in every floors in the skybrideg to reduce bad influence of 2 towers swinging during the earthquake. And the friction pendulum bearings could reduce earthquake reaction of the building and could be reseted automaticly after qarthquake.
