Poor fire resistance of fibre-reinforced polymer (FRP) restricts its further application in construction structures. In this paper, a novel fibre-reinforced cementitious matrix confined concrete column (FRCMCC) using fireproof grout as the fibre matrix was developed, and experiments were conducted to establish its performance and analyse the mechanical properties under axial compression. The te...

In order to obtain a more controlled durability and long-term performance of concrete structures in chloride containing environment special care is needed in the design phase of reinforced concrete structures. The recent development of probability-based procedures has proven to give a more realistic basis for both durability design and condition assessment of reinforced concrete structures. Alt...

In recent years, the corrosion of steel reinforcement has become a major problem in the construction industry. Therefore, much attention has been given to developing methods of predicting the service life of reinforced concrete structures. The progress of corrosion cannot be visually assessed until a crack or a delamination appears. The corrosion process can be tracked using several electrochem...

In the present study, a new method for retrofitting reinforced concrete beam is introduced in which steel-concrete composite jackets containing steel fiber is used. For this purpose, 75% of the peripheral surface of reinforced concrete beams was initially reinforced using steel plates and bolts, and steel fiber reinforced concrete was used between the steel plates and the peripheral surfaces of...

Nearly no load bearing behaviour of reinforced concrete members allows such varied interpretations and complex discussions as the shear behaviour. Especially the three-dimensional problem of the punching shear failure of reinforced concrete members is internationally discussed. Nevertheless up to now, there is no unified design approach or even an overall accepted design model. Especially for l...

Several building codes are available for the design of concrete structures reinforced with FRP; nevertheless knowledge on their structural behavior in case of fire is lack and no reliable design method is available. The experimental data available in the literature about the behavior of fiber-reinforced composite materials as well as of concrete slabs reinforced with FRP bars or grids at high t...

Advances in the fields of polymers and composites have resulted in a major development of high strength fibre reinforced polymers (FRP). These materials offer great potential for cost-effective retrofitting of concrete structures. In response to the growing need for concrete repair and rehabilitation, an experimental program was conducted at the University of Manitoba in Winnipeg, Manitoba, Can...

ABSTRACT: The absence of explicit guidelines for the rehabilitation of existing pole structures was the motivation to investigate the effectiveness of steel jacketing for the retrofitting of self-supporting steel and reinforced concrete telecommunication poles. The present study describes a numerical simulation of preand post-retrofitted conditions of the pole structures subjected to seismic ha...
