| 摘 要： | 钢桁梁结构具有跨度大、承裁能力强、结构轻巧简洁等特点,广泛应用于工程项目中.目前在设计时通常采用简化的计算方法,一般均假定桁架结构为铰接,进而计算桁架杆件的轴向应力事实上上述假定同实际情况并不完全相符,节点不是理想的铰.对铰接和刚接两种模型进行比较分析,并通过实例验证,阐述了铰接和刚接模型对钢桁梁设计的影响.

| Abstract: | The steel truss features large span,high bearing capacity,light and forthright structure.At present,designers usually adopt simplified computation method.Generally we assume that the truss structures are hinged models firstly,and then calculate the truss axial stress.In fact,the node is not an ideal hinge.This paper analyzes hinged and consolidation models in the design of steel truss,and expounds the influence of hinged and consolidated models on the steel truss design. |
