Research areas
Bamboo and engineered bamboo for structural applications
Bamboo is one of the fastest growing natural renewable materials with tremendous potential for use in construction. However, its wider application in traditional construction is restricted due to its limited size and natural non-uniformity. Engineered bamboo products such as laminated bamboo lumber, parallel bamboo strand lumber and glue laminated bamboo (GluBam) are becoming more popular due to their higher cost effectiveness, their versatility to suit specific design needs and considerable high strength-to-weight ratio.
Our researchers are collaborating with Nanjing Forestry University, who are one of the world leaders in bamboo engineering, to develop design rules for promoting the use of structural bamboo products. We are also working closely with INBAR (International Network for Bamboo and Rattan) to develop ISO standards for various aspects of bamboo including testing, mechanical characterisation and design.
Business value chain
A sustainable value chain is needed to transform newly developed materials from idea to reality. We have the expertise to propose sustainable ways to enhance business efficiency by delivering the most value of a novel material at the lowest cost. While proposing a solution, we consider logistics, operations, sales and marketing, supply chain, technological advancement, human resources, and infrastructure.
We have strong capabilities in interdisciplinary areas of industrial engineering and business value chain, such as:
- technological and organisational analysis and studies
- business data analytics for product life cycle assessments
- operations management of the value chain for performance or process reengineering.
Engineered timber products
Engineered timber products are becoming more popular in the construction sector due to the environmental benefit. Mass timber products such as laminated veneer lumber, glue laminated timber, cross-laminated timber and nail laminated timber are widely used for mid-rise construction. Mass timber products are also used to develop hybrid structural systems to complement the benefits offered by other traditional construction materials such as steel and concrete.
Our research team have been working closely with a number of major Australian timber producers, such as AKD Softwoods and XLam, to conduct design-oriented as well as fundamental research including:
- developing mechanical characterisation of Australian produced radiata pine CLT
- structural performance of hardwood-softwood hybrid CLT and their optimisation
- advanced numerical models for engineered timber products with special focus on fracture behaviour, and structural performance of innovative connection systems in timber construction
- adopting the circular economy concept in developing new products from reclaimed wood for connection system, including densified timber products and dowel-laminated timber.
Timber-composite structures
In order to use timber for long-span and multistorey construction, it's beneficial to increase the load carrying capacity of timber members using lightweight materials. We've used basalt, carbon and glass fibre reinforced polymer along with various engineered timber products. To evaluate the bond performance, we examine fracture and bond properties of the interface.
Our team has expertise in investigating various manufacturing techniques for producing timber-FRP composite structural elements that suit a particular application. We have additional expertise in:
- strategic placement of FRP using optimisation techniques
- numerical simulation of FRP-timber interface considering continuum damage mechanics and fracture mechanics-based approach
- developing design guidelines for FRP-timber composite structural elements.
Wood and timber
The properties of timber can vary significantly due to the geographical location of trees and their species. Softwoods are mostly used in construction, but hardwoods are becoming increasingly common worldwide largely due to their additional strength and stiffness.
Our group has extensive experience in:
- conducting experimental testing to characterise elastic, strength and fracture properties of both softwood and hardwood in three orthogonal directions of wood
- constitutive modelling of timber, considering its anisotropic behaviour, numerical simulation of timber as a material for finite element analysis
- conducting dynamic analysis to determine the material properties of wood non-destructively and condition assessment of timber structures.
