Rectangular Column Database

This database is provided by extending the one presented by Ghannoum et al. (2015) entitled “NEES: ACI 369 Rectangular Column Database”, which can be found on https://datacenterhub.org/resources/255. In this extended version, two new terms including the yield drift ratio and the displacement ductility demand are added to the original database through available technical reports, articles, and dissertations in the literature, since the latter parameter plays a key role in estimating the shear strength of reinforced concrete columns. This database provides wide range of information about 325 tested rectangular columns including geometry details of columns’ sections, mechanical properties of concrete and reinforcing steel, configuration of transverse and longitudinal reinforcements, loading patterns, and the measured results that can be employed by researchers to conduct numerical studies in the context of structural/earthquake engineering.

本数据集由Ghannoum等人（2015年）发布的题为《NEES：ACI 369矩形柱数据库》的数据集扩展而来，原始数据集可通过https://datacenterhub.org/resources/255获取。在本扩展数据集中，研究人员通过梳理文献中的现有技术报告、期刊论文与学位论文，向原始数据库新增了两个参数：屈服位移角（yield drift ratio）与位移延性需求（displacement ductility demand）。鉴于位移延性需求是预估钢筋混凝土柱抗剪承载力的核心参数，因此将二者纳入数据集以完善其内容维度。本数据集涵盖了325根经试验验证的矩形柱的多维度信息，具体包括柱截面几何细节、混凝土与钢筋的力学性能、横向与纵向钢筋的配置形式、加载模式，以及实测试验结果，可供结构工程/地震工程领域的研究人员开展数值模拟研究使用。
