A collaboration between Monash University and Coates Engineering Solutions is using high-strength steel, common to the automotive industry, to develop a lightweight high-capacity propping solution for temporary construction works.
The innovative solution, called Quadshore, has undergone rigorous destructive and non-destructive experimental tests in accordance with Australian Safety Standards, to demonstrate the durability and superior performance of the product.
Lead academic researcher, Associate Professor Amin Heidarpour, from Monash University’s Department of Civil Engineering said high-strength steel has not been efficiently utilised in temporary structures due to its limited plasticity.
“Quadshore contains hybrid components that creatively maximises optimum use of both high-strength and mild-steel to create lightweight, high-strength structural elements and boltless connections,” he said.
“The unique experimental facilities and lab environment at Monash’s Civil Engineering Department allowed our team to undertake the experimental tests on this product that replicated its behaviour in real-world settings.”
With a working load limit of up to 170 tonnes, it is the lightest heavy-duty structural propping system available anywhere in the world.
Over the past ten years research students and staff at Monash’s Civil Engineering’s Labs have worked on materials and concept studies for this project, culminating in a multi-year collaboration with Coates Engineering Solutions.
The research conducted by the last PhD student, Dr Esmaeil Pournamazian Najafabadi, addressed the challenges with heavy conventional props, that are mainly made from mild steel with low capacity-to-weight ratios.
“Our research has shown that by using high-strength steel we have been able to enhance the sustainability credentials of temporary structures where the carbon emission and energy consumption for manufacturing of Quadshore beams is at least 30 per cent lower than conventional props,” Associate Professor Heidarpour said.
“Industry benchmarks have measured the success of our product in terms of construction time, cost saving, safety enhancing features and sustainability credentials.”
