Experimental Database of Exposed Column Base Connections: Mechanical Behavior Insights and Predictive Models

2026

Abstract

This data paper presents an assembled experimental database comprising 157 physical tests on exposed column base (ECB) connections that were conducted worldwide over the past 40 years. The gathered data include fully digitized monotonic and cyclic base moment-base rotation relationships. The metadata include the loading conditions, the ECB types, and their material and geometric properties. The compiled database is used for the qualitative and quantitative assessment of available design models for the flexural strength and rotational stiffness of ECB connections according to the American and European design practices. The actual flexibility of conventional pinned ECB connections is explicitly quantified. The collected data suggest that when the rotational capacity of ECB connections relies on anchor yielding, the extent of column damage can be minimized. The database presented is publicly available.

Object database

An object database or object-oriented database is a database management system in which information is represented in the form of objects as used in object-oriented programming. Object databases are different from relational databases which are table-oriented. A third type, object–relational databases, is a hybrid of both approaches. Object databases have been considered since the early 1980s. Object-oriented database management systems (OODBMSs) also called ODBMS (Object Database Management System) combine database capabilities with object-oriented programming language capabilities.

Big data

Big data primarily refers to data sets that are too large or complex to be dealt with by traditional data-processing application software. Data with many entries (rows) offer greater statistical power, while data with higher complexity (more attributes or columns) may lead to a higher false discovery rate. Though used sometimes loosely partly because of a lack of formal definition, the interpretation that seems to best describe big data is the one associated with a large body of information that we could not comprehend when used only in smaller amounts.

Data

In common usage and statistics, data (USˈdætə; UKˈdeɪtə) is a collection of discrete or continuous values that convey information, describing the quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted formally. A datum is an individual value in a collection of data. Data is usually organized into structures such as tables that provide additional context and meaning, and which may themselves be used as data in larger structures.
