摘要
影响大型幕墙钢结构设计的因素较多,包括风荷载作用下的变形挠度控制、投影面积较大的外立面钢结构幕墙在温度作用产生的内力计算,以及针对支座刚度假定和主体结构的刚度影响也必须充分考虑,同时必须在充分考虑主体结构体系的情况下,采用与之相适应的幕墙钢结构受力体系也非常关键。综合各方面要素,对钢结构幕墙的结构形式进行方案选择,通过结构方案模型的分析,对结构模型的各项指标进行判别,确定出合理的结构形式;最后通过分析、总结,为相似的工程项目提供参考实例。
There are many factors affecting the design of large curtain wall steel structure,Including the deformation under the wind load deflection control,calculation of internal force generated by temperature action of steel curtain wall with large projection area,at the same time the stiffness assumption of the support and the influence of the stiffness of the main structure must be fully considered;at the same time,the main structure system must be fully considered.It is also very important to adopt the corresponding stress system of curtain wall steel structure.Integrate all the elements,select the structural form of steel curtain wall,through the analysis of the structural scheme model,discriminant the indexes of the structural model,choose a reasonable structure form.Finally,through summary and optimization,provides the reference instance example for the similar project.
