摘要
采用有限元ANSYS建立双角钢十字组合截面构件模型,并通过试验对模型进行校准。在此基础上,考察了构件的受力过程和破坏模式,分析了填板数量、布置方式、形式及填板与角钢连接方式等参数对节点极限承载力的影响。提出了计算此类构件承载力的计算公式,以便为工程设计提供依据。
The members with combined angle iron cross-section are widely used in electric transmission towers and the behavior is complex. In this study, the finite element analysis were conducted to study the compressive behavior of mem-bers with combined angle iron cross-section, and adjusted across experiments in the paper. On the basis , the influence of filled plate is studied on the ways of numbers, arrangement, shapes and the connection mode. Finally, theoretical formu-las are provided for engineering design.
