Steel I beams or girders with sinusoidal corrugated profile webs have become popular in the recent development of the steel structural designs, since corrugated-web beams (CWBs) can provide better performance in terms of less deformation and more stability against buckling failure. It is verified in previous research that CWBs can be considered as an alternative to replace normal beams in the structural designs with their numerous favourable features. Since CWBs are being used as the main structural elements, it is apparent that some essential practical properties of this type of beams should be studied, where the prediction of the shear capacity is one of the most significant design aspects that should be accurately investigated. Calculations to the design formulas from other standards and several finite element simulations have been carried out to compare the differences in obtained results and to find an adequate approach to calculate the shear capacity of CWBs for the Australian civil engineering community. Ultimate Limit State design theory has been utilised in conjunction with AS4100 (2017) along with linear analysis in SAP2000. By comparing the results of the theoretical calculations and numerical simulations, it has been concluded that the highly formed equations presented by EN 1993-1-5 (Design of Steel Structures Part 1–5: Plated Structural Elements, Eurocode 3, Brussels, 2006), Hancock et al. (2012) could well estimate the shear capacity constraining requirements and rules in accordance with Australian standards, which can be adequately used in Australian structural design fields.

基于第一屈服的波纹腹板焊接钢工字形梁的抗剪承载力分析

在钢结构设计的最新发展中,具有正弦波纹状轮廓腹板的I型钢梁或大梁已成为流行,因为波形腹板梁(CWBs)可以提供更好的性能,因为它的变形较小,并且抗屈曲破坏的稳定性更高。在先前的研究中已经证明,CWBs可以被认为是具有众多有利功能的结构设计中的普通梁的替代品。由于CWB被用作主要的结构元件,很明显,应该研究这类梁的一些基本实用特性,其中预测剪切力是应准确研究的最重要的设计方面之一。已根据其他标准对设计公式进行了计算,并进行了一些有限元模拟,以比较所得结果的差异,并找到一种适当的方法来计算澳大利亚土木工程社区的CWB的抗剪承载力。极限极限状态设计理论已与AS4100(2017)一起用于SAP2000中的线性分析。通过比较理论计算和数值模拟的结果,可以得出结论,EN 1993-1-5(钢结构设计第1-5部分:电镀结构元件,欧洲规范3,布鲁塞尔,2006年)提出了高度形成的方程式。 ,汉考克(Hancock)等人。(2012年)可以很好地估算出符合澳大利亚标准的剪切力约束要求和规则,
