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。
The concrete body of the Guangxi Science and Technology Museum is a reinforced concrete frame structure. The steel structure is used for the arc and the complex shape of the outer surface. The building has 4 floors above ground and 1 underground floor, and the highest point elevation is 47m. Due to the complex modeling of engineering buildings, it causes great difficulties for design and construction. It mainly introduces the design process and buckling analysis of the main frame and main entrance steel truss, the results of geometric nonlinear analysis, and the problems encountered in the design and Solutions, and suggestions for this type of structural design, for architectural modeling complex engineering reference.
