Fatigue Strengthening of Metallic Bridges using Carbon Fibre Reinforced Polymer System. A large number of metallic structures such as bridges, offshore platforms and large mining equipment are aging. Retrofitting such structures is becoming increasingly important in the 21st century. Using an advanced material, Carbon Fibre Reinforced Polymer (CFRP), to strengthen metallic structures is very promising. This project aims to develop reliable CFRP strengthening systems for aging metallic bridges. I ....Fatigue Strengthening of Metallic Bridges using Carbon Fibre Reinforced Polymer System. A large number of metallic structures such as bridges, offshore platforms and large mining equipment are aging. Retrofitting such structures is becoming increasingly important in the 21st century. Using an advanced material, Carbon Fibre Reinforced Polymer (CFRP), to strengthen metallic structures is very promising. This project aims to develop reliable CFRP strengthening systems for aging metallic bridges. It aims to make a breakthrough in understanding of the fatigue crack propagation in CFRP-metal composite system under combined loading. It intends also to produce practical guidelines for engineers to strengthen aging metallic bridges.Read moreRead less
Structural Fuses for Safer and More Economical Bridge Construction. This project aims to develop a novel structural system leading to more economical concrete bridge construction by utilising a customised structural fuse. A significant margin of safety is required in structural design to account for accidental over-loading and to reduce the risk of structural collapse. Such a margin leads to more material usage. Incorporation of a fuse into the structure that is triggered upon over-loading will ....Structural Fuses for Safer and More Economical Bridge Construction. This project aims to develop a novel structural system leading to more economical concrete bridge construction by utilising a customised structural fuse. A significant margin of safety is required in structural design to account for accidental over-loading and to reduce the risk of structural collapse. Such a margin leads to more material usage. Incorporation of a fuse into the structure that is triggered upon over-loading will cause a safer failure mode and prohibit further increase of loading, both of which result in a reduced structure without undermining safety. The project is expected to advance structural theory, and also provide significant benefits to the construction industry via cost reduction and more eco-friendly constructions.Read moreRead less
Thermal Upheaval Buckling of Functionally Graded Pavement Slabs. Upheaval buckling or blowup of concrete pavements due to high environment temperature is a serious problem in transportation infrastructure which quite often leads to road failure or even traffic hazards. The proposed project presents a combined theoretical, numerical and experimental investigation on the effective enhancement of thermal buckling capacity of pavement slabs with or without initial imperfection by using light and gre ....Thermal Upheaval Buckling of Functionally Graded Pavement Slabs. Upheaval buckling or blowup of concrete pavements due to high environment temperature is a serious problem in transportation infrastructure which quite often leads to road failure or even traffic hazards. The proposed project presents a combined theoretical, numerical and experimental investigation on the effective enhancement of thermal buckling capacity of pavement slabs with or without initial imperfection by using light and green functionally graded concrete materials with reduced usage of plain Portland cements for less carbon dioxide emissions. The research outcomes will contribute significantly to the society by offering a novel environmental friendly pavement solution with greatly improved road safety.Read moreRead less
