摘要
深圳观澜版画艺术博物馆采用钢筋混凝土框架-剪力墙与钢桁架的混合结构,结构体系较复杂。结构的屋面及上部楼层由跨度达40～54m的钢桁架组成,钢桁架支承于4个剪力墙筒体上,局部存在悬挑。结构内部空旷,楼板开洞较大,同时存在楼面标高复杂和楼板不连续的情况,属于平面和立面不规则的复杂高层结构。针对结构特点,进行结构弹性分析、钢桁架结构形式对比分析、混凝土收缩徐变分析、温度效应分析、舒适度分析、节点有限元分析。根据各项分析结果,采取有针对性的设计措施,取得明显的综合技术和经济效益。
The main structure of Guanlan Graphic Arts Museum consisted of reinforced frame-shear wall and steel truss system is very complex. The roof and upper floor of the structure is a spatial steel truss supported by 4 shear wall cores, part of which is cantilever. The floor system with partial opening and discontinuity is irregular in hoth plane and elevation. Thus, elastic analysis, structure style comparison, the analyses of concrete shrinkage, temperature variation and occupancy comfort etc were carried out, according to all the analytic results design measures were taken, with which obvious technical and economic benefits were obtained.
