Dr. Shanaka Kristombu Baduge is a postdoctoral research fellow of the Department of Infrastructure Engineering. He is working at CAMP.H (Centre for Advanced Manufacturing of Prefabricated Housing) funded by ARC and industry partners. He received his Ph.D. from The University of Melboune and he completed his B.Sc. (Hons) Eng. degree at University of Moratuwa. His Ph.D. focused on developing new mix-design methods for very-high strength concrete (VHSC) (100-150 MPa) and developing theoretical methods for ductility design of VHSC columns for tall-buildings.
Currently, he is the project leader for two projects involving industrial partners, Timber Building Systems and Australian Reinforcement Company. The recent change to the National Construction Code (NCC) allows timber buildings to increase in height to 25 m or 8 stories. He is working with TBS to develop a cost-effective and sustainable prefabricated panelised timber wall system for mid-rise buildings which can be deployed in a short duration. In the second project, he is working with ARC to develop a new waffle foundation system and also to develop a prefabricated foundation system for residential buildings. His skills and expertise include advanced structural analysis and design using finite element software such as ABAQUS, high performance materials, and structural optimisation.
His research interests include prefabricated building, prefabricated footing systems, high-strength and high performance concrete, light-weight structural systems, nanomaterial and nanoscale testing for construction material, multiscale modelling of concrete, low-carbon building material and generative design approach for structural optimization.
