3d-printed structural joint details for sustainability and robustness in steel frames

Project description

Innovative steel frame connection for buildings

The construction industry faces increasing demands to meet sustainability targets, reduce carbon emissions, and improve overall efficiency. Developing practical, innovative solutions to address these issues remains a significant challenge. Supported by the Marie Skłodowska-Curie Actions programme, the AM Joint project is developing a novel steel frame connection to replace traditional pinned joints in steel structures. This connection is designed to enhance structural safety and robustness. By using additive manufacturing (AM) techniques, the project aims to optimise the connection’s geometry and material use, achieving high load-bearing capacity while minimising waste. Its performance will be evaluated through both advanced numerical simulations and experimental testing, ensuring it meets the structural demands of modern, sustainable buildings.

Objective

The construction industry needs optimal solutions to meet sustainability goals, reduce carbon emission, decrease material
consumption and improve the speed of construction. In addition, economic and resource efficiency play a significant role in utilizing
new methods and technologies. Developing innovative construction techniques to meet all these criteria has been a challenging
topic recently. Therefore, the present study introduces a novel steel frame connection as an alternative to nominally pinned joints in
steel frame buildings, which in addition to providing safety under normal conditions, also significantly improves the robustness of the
frame in extreme conditions such as column loss, and prevents progressive collapse. The topology of the components will be
optimised to have a high capacity to sustain normal loads along with the tie forces due to column removal. Consequently, optimised
components will be constructed using additive manufacturing (AM) techniques that will result in savings in material consumption.
Considering a simple configuration that combines AM with traditional construction methods, the provisional connection will provide
a fast and easy assembly process. The efficiency and structural performance of the proposed connection under normal loads as well as
extreme tie forces will be evaluated through a comprehensive numerical and experimental study which is elaborated in the current
research proposal. A close connection with industrial partners and intensive interaction with other academic entities will ensure the
efficiency and effectiveness of the proposed connection. Comprehensive design guidelines along with quantified assessments of environmental and economic benefits will be developed in order to facilitate the practical application of the proposed connection.
