[摘要]郑州市民活动中心A区为大底盘多塔结构,地上四个主塔之间设有钢连接体,主塔采用框架-剪力墙结构,连接体与主塔之间采用隔震支座柔性连接,其中杂技馆与群艺馆之间的连接体为低位大跨度连接体,连接体采用型钢桁架。对该连接体的抗震支座进行分析选型,且对承托抗震支座的型钢混凝土柱进行性能设计。重点分析在小震和大震作用下,带连接体整体模型和不带连接体整体模型的动力响应特性和整体参数指标,论证了采用柔性连接的连体结构设计时,可通过在支座节点处施加竖向荷载的方式,考虑连接体的传力。

Abstract:The District A of Zhengzhou Civic Activity Center is a large chassis multi-tower structure. The main tower is provided with a steel connection between the four main towers on the ground. The main tower is a frame-shear wall structure. The connection between the connected body and the main tower is made up of a flexible connection of isolation supports, in which the connection between the acrobatic house and the group art house is large and low. The connecting body adopts steel truss, the seismic support of the connecting body was analyzed and selected, and the performance design of the type steel concrete column bearing the aseismic support was carried out. Emphasis was put on the analysis of the dynamic response characteristics and overall parameters of the whole model with and without connectors under the action of small earthquakes and large earthquakes. It is demonstrated that the design of a flexible connected structure can be carried out by means of the vertical load on the bearing joints.

Keywords:District A of Zhengzhou Civic  Activity Center; connected structure; flexible connection; steel truss; performance design
