Abstract

There is currently no specific rules in Part 1-2 of Eurocode 3 for the stability verification of non-uniform members under fire conditions. For normal temperature, Part 1-1 of the same code provides a General Method to check the stability against lateral and lateral-torsional buckling for these type of members, though it requires some extensive calculations. It is here demonstrated in this paper how both problems can be addressed, by exposing a procedure that accounts for the modifications of the method at elevated temperatures, and by showing its implementation within a computer program. It is also shown how the program can be used to assess the study of the method itself, by applying it to a case of a web-tapered beam-column and comparing it to numerical results.
非均匀构件稳定性验证软件。将通用方法程序应用于火灾设计
目前,欧洲法规第3部分第1-2部分没有关于非统一构件在火灾条件下稳定性验证的具体规则。对于常温,同一规范的第1-1部分提供了一种通用方法来检查这类构件的侧向和侧向扭转屈曲稳定性,尽管它需要一些广泛的计算。在这里,本文演示了如何解决这两个问题,通过暴露一个过程来解释在高温下方法的修改,并通过展示其在计算机程序中的实现。通过将该程序应用于一个腹板锥形梁柱的实例,并将其与数值结果进行比较,还说明了该程序如何用于评估方法本身的研究。
