This study presents the results of an experimental program to investigate the effectiveness of an innovative combined FRP technique using combination of externally bonded (EB) FRP fabrics and near surface mounted (NSM) FRP rods for flexural strengthening of existing reinforced concrete (RC) two-wayslabs with low clear cover thickness. Three full-scale RC slabs (1500×1500×120 mm) were tested und...

In this paper, a method to obtain crack initiation, location and width in concrete structures subjected to bending and instrumented with an OBR system (Optical Backscattered Reflectometer) is proposed. Continuous strain data with high spatial resolution and accuracy are the main advantages of the OBR system. These characteristics make this Structural Health Monitoring (SHM) technique a useful t...

This study evaluates the fire resistance performance (1–2h) of a reinforced concrete (RC) structure-void slab using a lightweight hollow sphere, which can reduce the unnecessary dynamic of removing the central concrete. For this experiment, we set up the depth of the concrete cover, live load, and span length as the factors. The result comes out with 50 mm cover depth of the RC structure hollow...

Accepting the challenge of the future in the field of civil engineering smart structure applications, the province of Manitoba is undertaking the responsibility of constructing the first bridge in Canada totally prestressed and reinforced for shear by cru:bon fibre reinforced plastic (CFRP) reinforcement. Portion of the concrete deck slab is also reinforced exclusively by FRP reinforcements. Th...

Reinforced concrete structures need to be strengthened and retrofitted for various reasons, including errors during design and/or construction, so in most cases strengthening of structural elements is much more economical than rebuilding the structure. Using HPFRCC with tensile stiffening behavior has been developed to strengthen the concrete structures over the recent few years. In this paper,...
