摘要
钢管结构近几年在我国得到广泛的应用,进行分析设计时一般采用以下几种计算模型,第一种是钢管结构所有杆件均采用杆单元,第二种是弦杆采用梁单元、腹杆采用杆单元,第三种是所有杆件均采用梁单元。在实际工程设计中,许多工程采用不同的计算模型得到的分析结果相差不多,但有些工程则相差很大,本文以实际工程为例对钢管结构计算模型的选取进行分析对比,从而得到一些有益的结论。
Steel tubular structures have been applied widely in our country in recent years.Several computational models are usually used while analyzing and designing as follows.The first model is that all of the tubular structure members are simulated as link elements.The second one is that chord members are seen as beam elements while brace members are link element.Third,all of the members are analyzed as beam elements.As to practical structure design, the difference among analysis results of different computational models is small in many structures,but still some ones difference a lot The analysis and contrast are proceeded to select the computational model of steel tubular structures by taking an actual structure as an example,and some helpful conclusions are obtained.
