ACI 369 Circular Column Database

The American Concrete Institute (ACI) committee 369 (Seismic Repair and Rehabilitation) is in the process of updating provisions pertaining to reinforced concrete structures of the American Society of Civil Engineers (ASCE) Standard 41-06 Supplement No.1 (2007) entitled "Seismic Rehabilitation of Existing Structures". This database is part of that ACI 369 committee effort. The circular column database is one of two parts of the ACI 369 column database. The database was compiled by Balaji Sivaramakrishnan and Dr. Wassim Ghannoum at the University of Texas at Austin and builds on the PEER Structural Performance database (http://nisee.berkeley.edu/spd/index.html). In turn, the PEER database was based on databases built by researchers at the National Institute of Standards and Technology (NIST) - (Taylor and Stone, 1993; Taylor et al., 1997). The PEER column data was collected and processed by University of Washington students Michael Berry, Haili Camarillo, Amit Mookerjee, Myles Parrish, and Zachary Price under the supervision of Professor Marc Eberhard. The database is made public through the NEEShub website to facilitate knowledge transfer to the community thus allowing users of ACI 369 documents and the ASCE 41 standard to evaluate the data on which the provisions are based. Posting the database online also serves to facilitate updating of the database with additional experimental data. We encourage the community to point out any column tests that have been omitted in the database or submit any new experimental data that can be added to the database. Please contact Dr. Ghannoum at ([e-mail]) if you would like to contribute to this database. Any data submitted will be processed and verified by ACI committee 369 before being posted. The data are organized and presented as a spreadsheet: each row contains information about one test and the columns contain information about geometry, reinforcement details, strength of materials, drift ratio at different level of loading, lateral load, shear capacity, and lateral load-deflection data files. Data files can be downloaded in CSV formats.

美国混凝土协会（American Concrete Institute, ACI）369委员会（抗震修复与加固专业委员会）正在修订美国土木工程师协会（American Society of Civil Engineers, ASCE）标准41-06第1号补编（2007年）《既有结构抗震加固》中的相关条款。本数据集正是ACI 369委员会此项工作的组成部分。圆形柱数据集是ACI 369委员会柱数据集的两个子部分之一。该数据集由德克萨斯大学奥斯汀分校的Balaji Sivaramakrishnan与Wassim Ghannoum博士编制，其数据基础源自太平洋地震工程研究中心（PEER）结构性能数据库（http://nisee.berkeley.edu/spd/index.html）。而PEER结构性能数据库的数据源，则依托于美国国家标准与技术研究院（National Institute of Standards and Technology, NIST）研究人员构建的相关数据集（Taylor与Stone, 1993；Taylor等人, 1997）。PEER柱数据集由华盛顿大学学生Michael Berry、Haili Camarillo、Amit Mookerjee、Myles Parrish及Zachary Price在Marc Eberhard教授的指导下完成收集与处理工作。本数据集通过NEEShub网站公开，旨在推动学术社区间的知识共享，方便ACI 369系列文件及ASCE 41标准的使用者评估标准条款所依托的试验数据。同时，线上发布该数据集也便于后续补充更多试验数据以完成版本更新。我们诚挚呼吁学界同仁指出本数据集遗漏的柱体试验案例，或提交可纳入本数据集的新型试验数据。若您有意向为本数据集贡献内容，请联系Wassim Ghannoum博士（邮箱：[e-mail]）。所有提交的数据在正式公开前，均需经过ACI 369委员会的审核与验证。本数据集以电子表格形式组织与呈现：每一行对应一项独立试验的完整信息，各列分别记录几何参数、配筋构造细节、材料强度、不同荷载水平下的位移角、侧向荷载、抗剪承载力以及侧向荷载-位移数据文件。数据文件可通过CSV格式下载。
