Mixed Mode Torsion-Shear-Bending Failure in SFRC Elements . In 2017 and 2018 the Australian Standards for the design of concrete bridges and structures were released; these are some of the first in the world, to include design procedures for steel fibre reinforced concrete (SFRC) in a comprehensive way. While rules have been introduced for shear and bending of SFRC girders, the rules exclude the use fibres to carry torsional moments.

The behaviour and design of innovative connections to promote the reduction and reuse of structural steel in steel-concrete composite buildings. This proposal will study the behaviour of innovative connections to promote the reduction and reuse of structural steel in steel-concrete framed buildings. Steel is one of the most recycled materials on earth, however it is the reduction and reuse rather than recycling which can provide significant benefits to building construction.

This proposal will study the behaviour of innovative connections to promote the reduction and reuse of structural steel in steel-concrete framed buildings. Steel is one of the most recycled materials on earth, however it is the reduction and reuse rather than recycling which can provide significant benefits to building construction. Economic and technical issues have impeded the widespread application of the reuse of steel. These technical impediments can be addressed through the development of connections that promote dismantling of structures at the end of a building's life. This project will address this issue by developing innovative structural connections through experimental and analytical studies and design code provisions.Read moreRead less
Rotation Capacity of Joints in SFRC Moment Resisting Beams and Frames. In January 2014 the draft Australian Standard for the design of concrete bridges was released; this is the first standard in Australia, and one of the first in the world, to include design procedures for steel fibre reinforced concrete (SFRC) in a comprehensive way. While rules have been introduced for flexure and shear, strict limitations are placed on application where large plastic rotations are expected.

In January 2014 the draft Australian Standard for the design of concrete bridges was released; this is the first standard in Australia, and one of the first in the world, to include design procedures for steel fibre reinforced concrete (SFRC) in a comprehensive way. While rules have been introduced for flexure and shear, strict limitations are placed on application where large plastic rotations are expected. This study investigates the moment-rotation performance of SFRC beam-column connections containing economical fibre dosages. The study is expected to provide data on the post-ultimate behaviour and robustness of SFRC moment hinges and determine moment-rotation relations for adoption by engineers and Standards bodies.Read moreRead less
