In this paper, the strengthening of two-way slabs using CFRP sheets is evaluated experimentally. The reinforcement ratio equal to 1.29% was chosen to serve the purpose of demarcating the punching shear failure mode. Results show that the punching capacity of two-way slabs can increase to 40% over that of the reference specimen. However, since bridge deck slabs directly sustain repeated moving wheel loads, they are one of the most bridge elements susceptible to fatigue failure. Therefore, this research is designed to

Nine one-way concrete slabs reinforced with carbon-FRP bars were constructed and tested to failure under two-point loading. The effect of reinforcement ratios, bar diameters, and various concrete compressive strengths were investigated to determine the concrete's contribution to shear strength. Slab structural behavior in terms of crack patterns, modes of failure, and ultimate capacities were examined. All slabs ultimately failed in shear that caused rupture and complete separation of both parts of the slab. One of the tested

The paper describes a comprehensive experimental program involving 4 large- scale wall specimens, one reinforced with steel bars (as reference) and three totally reinforced with GFRP bars. Reinforcements were detailed to represent single medium-rise shear wall in regions of low to moderate seismic risk. All walls failed due to concrete compression failure, reaching their flexural capacities with no strength degradation, controlling shear, sliding shear, and anchorage failures. The results show recoverable

ABSTRACT Experimental analysis of reinforced shear-wall with glass-fiber reinforced polymer (GFRP) showed its applicability in resisting lateral loads with no strength degradation, acceptable deformation capacity and energy dissipation as illustrated in an earlier article by the authors. The observed performance of GFRP-reinforced shear walls strongly suggested the necessity of proposing design procedure for such lateral resisting member. To propose design guidelines, however, determination of the elastic

In the numerical analysis of engineering problems, it is often necessary to properly model the behavior and effects of discontinuities and interfaces. The parameters of the experimental and analytical programs were the concrete compressive strength and shear span-depth ratio. Discrete and smeared ways of analysis of the bond link element were used. Effort has been given using non-linear 3D FEM program to predict the punching shear failure mechanism and the crack pattern of open sandwich slabs. Based on the analytical

With the establishment of several construction applications of FRP reinforcement, there is a need for a system to resist lateral loads induced from wind and earthquake loads in these constructions. Reinforced concrete shear walls have shown effective performance in resisting lateral loads caused by wind and earthquake loads. Therefore, shear walls are frequently used in parking garages and multi-story buildings exposed to high lateral loading. This research involved testing a shear wall totally

Fiber-reinforced polymer (FRP) materials have proven their effectiveness as an alternative reinforcement for concrete structures in severe environmental conditions. Many studies have investigated the flexural and shear behaviors of FRP-reinforced concrete beams and slabs. Limited research, however, has gone into investigating the behavior of internally reinforced FRP concrete columns. This paper reports the experimental investigation of the compressive performance of concrete columns reinforced

Few studies are available on members reinforced internally with fiber-reinforced polymer (FRP) bars and subjected to compressive axial load; therefore, the behavior of FRP internally reinforced concrete columns has not been well established. In this paper, experimental results of 23 nearly full-scale square concrete columns reinforced transversally with glass FRP (GFRP) and carbon FRP (CFRP) ties, and longitudinally with GFRP, CFRP, and steel bars, and subjected to concentric monotonic axial compression
