Review on Mixing Proportion of Design of High-Performance Concrete Exceeding 80 MPa

This paper presents the mixing proportion of high-performance concrete (HPC) having compressive strength over 80 MPa. This type of concrete comprises of almost con-stituents with fine particles and often having additional steel fibers in the mixture of HPC. The HPC showed excellent properties such as high compressive strength, high stiffness, improved toughness and durability compared…

Suitability of optimized truss model to predict the FRP contribution to shear resistance for externally bonded FRP strengthened RC beams without internal stirrups

Shortcoming in the current design guidelines on externally bonded FRP shear strengthened members has initiated a motivation to relook the whole shear design approach. It is understood that effective FRP strain models used in present design guidelines are basically calibrated from the experimental data based on the conservative and unrealistic 45-deg truss model. This paper…
