通辽市蒙古族服饰博物馆结构设计

Structural design on Tongliao Mongolian Costume Museum

通辽市蒙古族服饰博物馆由三个布局相似的单元组成,屋面为马鞍形双曲屋面,造型独特。结构采用框架-剪力墙结构体系,双曲屋面采用混凝土壳。设计时采用PMSAP软件进行整体计算,采用SAP2000软件对双曲屋面及其支承剪力墙进行了详细的有限元分析。结果表明,双曲屋面壳体沿纵向产生一定的拉力;沿短向由于拱的作用产生推力,使得楼板受拉;整体计算结果与单榀计算结果接近。可供类似工程设计参考。

Tongliao Mongolian Costume Museum is composed of three similar units. The roof is a saddle shaped double curved roof with special shapes. The structure adopts frame-shear wall structure system,and the hyperbolic roof uses concrete shell. PMSAP software was used for the overall calculation,and the SAP2000 software was used to perform finite element analysis on the hyperbolic roof and its supporting shear wall in detail. The results show that the hyperbolic roof shell produces a certain tension along the longitudinal direction; the thrust is produced along the short direction due to the effect of the arch,and the slab is pulled; the overall calculation result is close to the result of the single calculation.
