This paper investigates the effects of different parameters on the live load carrying capacity of concrete beams reinforced with FRP bars. The author performed a parametric study utilizing an innovative numerical approach to inspect the effects of multiple variables such as reinforcement ratio, concrete compressive strength, span to depth ratio, FR...
Finite-element analysis (FEA) and an analytical model were used to estimate the ultimate flexural strength of reinforced concrete (RC) beams with corroded compression bars. Both models accounted for the deteriorated material's properties and geometry. The two models were verified against available experimental data and both showed good agreement. T...
Load rating analysis of bridge live load capacity is the main technique in evaluating existing bridges in the United States. Load ratings are performed on a bridge following a detailed visual inspection mainly based on engineering experience. With the absence of an analytical evaluation procedure to determine the ultimate flexural strength of bridg...
In order to develop a cost-effective retrofit system for deteriorated concrete members, there is a need for sound evaluation of their remaining strength. Unfortunately, there is a lack of reliable models for evaluating the residual strength of steel reinforced concrete beams, and further, there is no simplified analytical model that can reasonably...
Corrosion is the primary limit state in steel reinforced concrete (RC) beams in severe environments. Corrosion of steel bars causes a decrease in steel bar section, loss of bond, and delamination of concrete cover Very limited models have been developed for estimating the residual flexural strength of corroded RC beam. These models do not different...
This paper investigates the parameters that control the design of Fiber Reinforced Polymer (FRP) reinforced concrete flexural members proportioned following the ACI 440.1R-06. It investigates the critical parameters that control the flexural design, such as the deflection limits, crack limits, flexural capacity, concrete compressive strength, beam...
