［摘要］邯鄲文化藝術中心包括博物館、大劇院、城規(guī)館和圖書館，采用鋼筋混凝土框架-剪力墻結構與鋼結構的混合結構。博物館和圖書館利用多層結構高度形成巨型懸挑鋼桁架，將部分樓層整體懸挑。外圍鋼桁架為空間曲面，結構形式復雜。大劇院上方的橢球形頂蓋采用雙向正交鋼管桁架體系形成雙層網(wǎng)殼結構。殼體平面尺寸為108m×85m，高度為22.5m。結構內(nèi)部空曠，樓板開洞較大，樓板標高復雜，造成樓板不連續(xù)。結構剛度分布不均勻。巨型懸挑鋼桁架和轉換結構造成抗側力構件豎向不連續(xù)。整體結構屬于復雜超限工程。針對結構特點，采用基于性能的設計方法，對重點部位制定了性能目標。采取了加厚樓板、設置樓板暗撐、加強墻體約束等抗震加強措施。采用多種程序分析了結構在不同地震水準作用下的彈性或彈塑性響應。補充了樓板應力分析、重要剪力墻應力分析、鋼結構穩(wěn)定分析、防止連續(xù)倒塌分析、殼體單獨模型分析等。結果表明，結構能夠?qū)崿F(xiàn)設計性能目標，具有良好的抗震性能。

Abstract:Handan Culture & Arts Center includes a museum, an opera house, an urban planning museum and a library. The main structure is hybrid with reinforced concrete frame-shear wall and steel structure. Some floors of the museum and library are cantilevered by multi-story height steel truss. The external surface is spatial steel truss and has a complex structure. Ellipsoidal roof of the opera house is a double layer latticed shell structure formed with two-way orthogonal steel truss system. The plane size of the shell is 108m×85m, and its height is 22.5m. The structure is complex and beyond the scope of design codes. The performance-based design method was used in seismic design. Specific performance objectives were developed for important structure elements. Some details of seismic design were adopted, such as thickening the floor, setting floor brace and strengthening the wall constraints. Several programs were used to analyze the elastic and plastic response of structure under earthquake of different levels. Some specialized analyses were supplemented, including stress analysis of large opening floors and important shear walls, stability analysis and progressive collapse analysis of steel structures, and independent shell model analysis. The results show that the performance objectives are achieved and the seismic performance of the structure is good.
Keywords:performance based seismic design; latticed shell; multi-story height cantilever steel truss; stability analysis; progressive collapse analysis; pushover analysis
