This paper presents an experimental study and theoretical analyses on the monotonic and fatigue performance in bending of a polyvinyl alcohol (PVA) fiber-reinforced engineered cementitious composite (ECC) overlay system. The influence of the interfacial characteristics between overlay and old concrete substrate on the overall bending performance is investigated. The experimental results show th...

When earthquakes occur, energy released by the earthquake gets induced into the structure as ground motion and this energy has to be dissipated for safety reasons. To release seismic energy, the structure should damage in such a way that on one hand, collapse of structure should not occur and on the other hand, after the earthquake, damage should be economically feasible to repair. To avoid the...

An analysis was carried out to determine whether concrete is a sustainable housing material. Sustainability generally means having no net negative impact on the environment, and this analysis compared the environmental impact of producing concrete and steel. To make this comparison, we first designed a simple reinforced concrete beam and a steel I-beam with the same moment capacity, and we then...

Debonding problems of externally bonded fiber reinforced polymer (FRP) sheets in flexurally FRP-strengthened reinforced concrete (RC) beams have been a concern and a research challenge since their application of this strengthening technique. Intermediate crack induced debonding is the most common failure mode which is that the debonding initiates at the critical flexural-shear or flexural crack...

The purpose of this research was to investigate the creep behaviour of the heterogeneous Timber-UHPFRC beams. New developments have been done to further improve the structural performance, such as strengthening of the timber (glulam) beam by bonding composite material combine with an ultra-high performance fibre reinforced concrete (UHPFRC) internally reinforced with or without carbon fibre rei...

This report describes a non-linear method of analysis for prestressed concrete structures which predicts behaviour at all stages of loading, from the initial application of prestress up to and beyond the collapse condition. The method uses a segmental line element approach and is a modification of an existing method previously developed for reinforced concrete structures. Comparisons with the r...

This study echoes the rising demand for bio-based material in concrete composite structures race to accelerate carbon neutrality construction. Noticing that most previous studies are focused on straight timber or engineered bamboo-to-concrete beams, this developed curved-and-tapered mechanically laminated bamboo-concrete (LBC) T-beams. Six layers of 26 mm thick bamboo panels were glue together ...

Common transverse reinforcement of reinforced concrete members with circular cross-section consists of round ties or spirals. Its purpose in members that are not subjected to significant shear loading is to provide proper confinement for concrete, and eliminate buckling of the longitudinal reinforcement bars. If spirals are to be used as both shear enabler and confiner for reinforced concrete b...

This paper presents results from Finite Element Modelling (FEM) of steel-concrete composite beams strengthened with prestressed Carbon Fibre Reinforced Polymer (CFRP) plate. For the purpose of this study, three beams were strengthened using prestressed CFRP plate with three different levels of induced prestressing force. The models were developed using ANSYS FE package. The results of an experi...
