Circular Column Database

This database is provided by extending the one presented by Ghannoum et al. (2015) entitled “NEES: ACI 369 Circular Column Database”, which can be found on https://datacenterhub.org/resources/254. 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 172 tested circular 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.

本数据库基于Ghannoum等人（2015年）发布的题为《NEES：ACI 369圆形柱数据库》的数据集扩展而来，该原始数据集可通过https://datacenterhub.org/resources/254获取。在本扩展版本中，研究人员通过公开的技术报告、学术论文及学位论文，向原始数据库中补充了两个新参数：屈服层间位移角（yield drift ratio）与位移延性需求（displacement ductility demand）；其中位移延性需求对钢筋混凝土柱的抗剪强度估算起到关键作用。本数据库涵盖172根经试验验证的圆形柱的丰富信息，包括柱截面几何细节、混凝土与钢筋的力学性能、横向与纵向配筋构造、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相关数值研究使用。
