Abstract Cold-formed metal deck is commonly used in the construction of modern buildings. It is readily available and cost effective in many applications. Conservative design tables provided by metal deck producers aid the engineer of record and encourage use of the product. The American Iron and Steel Institute has embraced advanced analysis techniques, particularly the Direct Strength Method and Effective Width Method, which can be used to analyze a variety of thin gage, cold-formed structural shapes, presumably including deck. These methods have become popular with designers, as they have shown to reflect accurate flexural capacities for many standard cold-formed shapes. Until recently, these methodologies have not been applied to the analysis of metal deck. The objective of this research initiative is to compare the results of both the Direct Strength Method and Effective Width Method to experimental results for several metal deck profiles and gages and evaluate the numerical methods' applicability to metal deck. The experimental program comprises 54 full-scale tests of several depths and gages of roof and floor deck. Experimental results are compared to results from numerical methods. It was found that both numerical approaches reasonably predicted the flexural capacity of shallow roof deck, but numerical predictions deviated from experimental results as deck became deeper. Thickness of the deck (gage) played a role, and as deck became thinner the numerical methods showed a larger discrepancy from experimental results.

冷成型金属甲板可接受设计方法的试验研究

摘要 冷弯金属桥面在现代建筑中普遍使用。它在许多应用中都很容易获得且具有成本效益。金属甲板生产商提供的保守设计表有助于记录工程师并鼓励使用该产品。美国钢铁协会采用了先进的分析技术，特别是直接强度法和有效宽度法，可用于分析各种薄规格、冷成型结构形状，大概包括甲板。这些方法已受到设计师的欢迎，因为它们已证明可以反映许多标准冷成型形状的准确弯曲能力。直到最近，这些方法还没有应用于金属甲板的分析。该研究计划的目的是将直接强度法和有效宽度法的结果与几种金属甲板型材和量规的实验结果进行比较，并评估数值方法对金属甲板的适用性。实验计划包括对屋顶和地板甲板的几个深度和规格的 54 次全尺寸测试。将实验结果与数值方法的结果进行比较。发现两种数值方法都合理地预测了浅屋顶甲板的抗弯能力，但随着甲板变深，数值预测与实验结果有所偏差。甲板的厚度（量规）起到了作用，随着甲板变薄，数值方法与实验结果的差异更大。
