The project will develop an analytical and computational basis for designing midrise buildings in cold-formed steel. It will enable solutions with high column capacities and high lateral load resistance to be realised by using built-up sections, thus overcoming the current barrier to constructing buildings up to 10 storeys from cold-formed steel and enabling green, fully recyclable and rapidly constructed buildings to be achieved. Experimental, analytical and computational studies will be undertaken and synthesised into efficient design guidelines for practising engineers, including structural reliability analyses at system level of midrise buildings featuring innovative built-up multi-section columns and integrated shear panels.Read moreRead less
Understanding the performance of cold-formed steel frame wall systems in fires to design for superior fire resistance. This project will develop new light gauge steel frame (LSF) wall systems with superior fire resistance rating and associated design rules to enable innovative and safe applications of these wall systems in various building applications. This will enable expansion of the worldwide market for LSF wall systems by the industry partner.
Built-up cold-formed steel structures. The building industry is seeing a rapid uptake of joining two or more cold-formed steel sections to form large built-up sections with high carrying capacities. The joining consists of screws, or similar fasteners, placed intermittently along the member. The ease of joining encourages innovation in forming versatile new built-up section shapes in expanding areas of application.

Summary
Interactions between volumetric units in modular buildings. This project aims to develop an in-depth understanding of the interactions between volumetric units in modular buildings to develop integration strategies for the interconnection of modules. The uptake of modular construction has been hindered by the technical complexities of the design process for manufacture and assembly, in particular the flexible connection of services. By addressing significant gaps in the guidance on the design of ....Interactions between volumetric units in modular buildings. This project aims to develop an in-depth understanding of the interactions between volumetric units in modular buildings to develop integration strategies for the interconnection of modules. The uptake of modular construction has been hindered by the technical complexities of the design process for manufacture and assembly, in particular the flexible connection of services. By addressing significant gaps in the guidance on the design of modular interconnections and their integration strategies, this project expects to enhance the industry’s capacity to adopt safe, economical and standardised designs of modular systems. This project should significantly reduce the risk in decision making in modular construction, and transformation to advanced building manufacturing technologies in Australia and beyond.Read moreRead less

The development of demonstrable cost-effective structural systems is essential if these types of systems are to be widely adopted in practice, thus allowing Australian manufacturers of blind bolts and steel tubes to achieve a greater market share.Read moreRead less
New Systems for High Rise Steel Structures in Rising Factory Construction. This project will develop new and innovative ways of constructing steel structures using the rising factory concept. The rising factory is a 10 storey enclosure where the final high-rise building is safely constructed within a watertight envelope which rises as the building progresses.

This project will develop new and innovative ways of constructing steel structures using the rising factory concept. The rising factory is a 10 storey enclosure where the final high-rise building is safely constructed within a watertight envelope which rises as the building progresses. The project will perform the necessary research to make possible high-rise steel structural systems consisting of hot-rolled (heavy gauge) and cold-formed (light gauge) steel structural members and connections which can be used in the rising factory. The main benefits of the rising factory are the waterproof construction environment and the substantially increased safety as a result of no external cranes.

Hybrid steel-framed structural systems for mid-rise buildings. The project aims to develop solutions for lightweight structural systems. Hybrid steel structures are those constructed from a mixture of conventional hot-rolled steel sections and tubes combined with lightweight cold-formed steel structural members. There is an increasing need to provide prefabricated structural systems that are highly constructible and modular in mid-rise (5–10 storeys) residential apartment and commercial building ....Hybrid steel-framed structural systems for mid-rise buildings. The project aims to develop solutions for lightweight structural systems. Hybrid steel structures are those constructed from a mixture of conventional hot-rolled steel sections and tubes combined with lightweight cold-formed steel structural members. There is an increasing need to provide prefabricated structural systems that are highly constructible and modular in mid-rise (5–10 storeys) residential apartment and commercial buildings. The major problem in producing efficient hybrid systems is the connections between the hot-rolled framing members and the lightweight cold-formed members. The main aim of the project is to carry out experimental and theoretical research into the hybrid connections. The expected outcomes of the research are more efficient and standardised structural connections and systems.Read moreRead less

A major international collaboration between researchers in Australia, New Zealand and Italy is underway to develop a method for structural engineers to determine which masonry buildings post a significant hazard to the public in the event of an earthquake such as that which struck the city of Christchurch.
Optimization of internal pressure for designing industrial buildings. The project seeks to understand the internal pressure in a building during windstorms, to improve safety and performance. The internal pressure in a building is dependent on its volume and flexibility and the sizes of openings in the building envelope, and is a critical loading parameter in building design. Windstorm damage investigations have shown that incorrect internal pressures are frequently used in building design, lead ....Optimization of internal pressure for designing industrial buildings. The project seeks to understand the internal pressure in a building during windstorms, to improve safety and performance. The internal pressure in a building is dependent on its volume and flexibility and the sizes of openings in the building envelope, and is a critical loading parameter in building design. Windstorm damage investigations have shown that incorrect internal pressures are frequently used in building design, leading to damage. This project aims to study the internal pressures generated in buildings with a range of volumes and openings in the envelope. A combination of model-scale and full-scale tests and theoretical analysis are planned to determine critical parameters for highly turbulent air-flow though openings. Results will inform the revision of design data in codes and of guidelines for consistent, optimal design of buildings.Read moreRead less
