Development and experimental testing of a new connection for structural steel sections (AMASS Project)
PhD project Description
Today’s urban environment and transportation networks rely heavily on the use of steel load carrying structures. Despite the two main steel connection methods, welding and bolting, being slow and/or expensive field activities, a new universally applicable, structural steel connection mechanism has not been introduced in more than a century. For a typical, multi-storey building, fabrication costs can rival the material costs. Furthermore, a major part of the steel frame cost is related to on site assembly and erection, with higher costs expected for more complex connections. In terms of weight, a standard allowance for these fittings and connections in this type of structure adds 5 – 10% to the total weight of the frame. While new manufacturing capabilities offer the potential to develop faster and more cost-effective connection methods, a major effort to this end has yet to be undertaken. By improving and refining these features of multi-storey steel buildings, considerable savings in both weight and cost could be achieved. To achieve these savings, improved construction efficiency and heightened material reuse, this research aims to design, develop and test an entirely new class of ‘’snap together’’ or ‘’interlocking’’ steel connections that rely on neither welding nor bolting, fabricated using precise, computer-controlled, advanced manufacturing techniques in plasma cutting, while being compliant with building design codes. Through the US-Ireland R&D Partnership, the collaborative international team in the Northern Ireland (Queen’s University Belfast), Republic of Ireland (University College Dublin) and US (University of Minnesota) are ideally placed at centres of excellence to deliver on the design, development and testing of this new steel connection (AMASS connection) created from advanced, volumetric cutting techniques.
