摘　　要：东海水晶博物馆是国内第一座以水晶为主题的博物馆,总建筑面积约2.7万m2,地下1层,地上5层,屋脊最大高度32.5m,设计使用年限100年。外形复杂,屋面为竖向折线形,东西方向的上下楼层通过40°或140°斜面连接在一起,酷似水晶原石。主体结构采用钢筋混凝土框架-剪力墙结构,所有斜面均采用现浇钢筋混凝土梁板,是一种形状比较特异的结构类型。在结构设计中,按100年取地震动参数,并考虑斜板的侧向刚度。采用PMSAP,MIDAS/GEN等不同软件对结构进行计算分析,并进行了多遇地震下的弹性时程分析和罕遇地震下的静力弹塑性分析,找出结构的薄弱部位,对薄弱部位进行了加强,保证抗震性能目标的实现。Donghai Crystal Museum Located at lianyungang city is the first crystal theme museum in China, with a total floor area about 27 000 m^2 , and one level basement and five level floors above the ground. The maximum ridge height is 32.5m, and the design service life is 100 years. The museum with a vertically coruggated roof and a complicated contour, which closely resembles the shape .of a crystal ore, is connected either by 40 degrees or by 140 degrees inclined planes for the upper and lower floor level along the east-west direction. The structure system adopted is rather exceptional： the RC frame- shearwall for main structure and the cast-in-situ RC concrete beams and slabs for the inclined planes. The 100-year dynamic seismo-parameters and the inclined plane lateral stiffness have been all taken into consideration in the structure design. The key factors of the structure were checked with different structure softwares such as PMSAP and MIDAS/GEN. To guarantee the objectives of performance-based seismic design, some controling weak spots were determined by means of the elastic time-history analysis under the frequent earthquake and nonlinear static analysis under the rare earthquake, and they are accordingly strengthened.
