［摘要］山东省科技馆新馆为特大型科技展馆，属于特别不规则的超限高层建筑。通过方案比选，采用了“钢筋混凝土框架-屈曲约束支撑（BRB）”结构体系。通过设置BRB，既满足控制扭转需要，又使结构成为消能减震建筑，提高结构抗震性能。除基础、地下室和上部结构设计外，重点分析了BRB设置的原则、位置以及型号，并对其进行了优化设计。通过详细的抗震性能分析和构造设计，确保结构达到预定的抗震性能目标；并针对夹层的影响、BRB实际减震效果，做了专题研究论证。

Abstract:The new Shandong Science and Technology Museum is a super-large science and technology exhibition hall, which belongs to a special irregular out-of-code high-rise building. Through comparison and selection of structural schemes, the structural system of reinforced concrete frame and buckling-restrained brace (BRB) was adopted. BRB can make the structure meet the needs of controlling torsion, create an energy dissipation building, and improve the seismic performance of the structure. In addition to the design of the foundation, basement and superstructure, the principle, location and model of the BRB settings were analyzed, and the optimized design was performed. Through detailed seismic performance analysis and structural design, the structure could achieve the predetermined seismic performance target, and a special study and demonstration was conducted on the impact of the interlayer and the actual seismic dissipation effect of BRB.
