［摘要］鄭州市民活動中心A區(qū)為大底盤多塔結(jié)構(gòu)，地上四個主塔之間設(shè)有鋼連接體，主塔采用框架-剪力墻結(jié)構(gòu)，連接體與主塔之間采用隔震支座柔性連接，其中雜技館與群藝館之間的連接體為低位大跨度連接體，連接體采用型鋼桁架。對該連接體的抗震支座進(jìn)行分析選型，且對承托抗震支座的型鋼混凝土柱進(jìn)行性能設(shè)計。重點(diǎn)分析在小震和大震作用下，帶連接體整體模型和不帶連接體整體模型的動力響應(yīng)特性和整體參數(shù)指標(biāo)，論證了采用柔性連接的連體結(jié)構(gòu)設(shè)計時，可通過在支座節(jié)點(diǎn)處施加豎向荷載的方式，考慮連接體的傳力。

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
