广西科技馆结构设计中若干问题

Structural design of reticulated shell with breaches of Guangxi Science and Technology Museum

广西科技馆混凝土主体为钢筋混凝土框架结构,外表面弧形及造型复杂处部分采用钢结构,建筑物地上4层,地下1层,最高点标高47m。由于工程建筑造型复杂,对设计和施工均造成较大的困难,主要介绍主体框架和主入口钢结构桁架设计过程和进行屈曲分析、几何非线性分析的结果,以及在设计中遇到的问题和解决方法,并对此类型结构设计提出建议,供建筑造型复杂的工程参考。

Guangxi Science and Technology Museum is the concrete frame which has the irregular cured external surface.And some parts of the structure are made by steel.The building is 4 stories,the height of building is 47m.For the complicated shape,it has trouble in design and construction.The two design process,concrete frame and steel structure are listed.The problems and solutions in design process are introduced,and then advices are given for this kind of building.
