Abstract

The column web panel is a fundamental component of beam-column joints. This component has been thoroughly studied and codified in the past. In this paper, new insight on its behaviour is obtained using a large amount of high-quality Finite Element (FE) models, covering a wide range of panel slenderness and aspect ratios. The study shows that the existing models in part 1-8 of the current and forthcoming Eurocode 3 present a wide scatter in terms of resistance and stiffness, being unconservative in some specific cases.

对网络面板组件的新认识
柱腹板是梁柱连接的基本组成部分。过去曾对该部件进行过深入研究和编纂。本文使用大量高质量的有限元 (FE) 模型对其行为进行了深入研究,这些模型涵盖了广泛的面板细长率和长宽比。研究结果表明,现行和即将颁布的 Eurocode 3 第 1-8 部分中的现有模型在阻力和刚度方面存在较大差异,在某些特定情况下不够严谨。
