A Study on the Capacity of Wide RC Beams
—
by
Computation of strength capacity of wide reinforced concrete (RC) beams was studied. Four design codes, ACI 318M-08, Eurocode 2-2004, AASHTO-2005, and CSA-2004, were adopted and used for the calculation. The computed results obtained from these codes were also compared with experimental results conducted by researchers, Khalil et al. (2019), and Shuraim (2012).

Prediction the Shear Strength for FRP Shear Strengthened RC Beams Based on Optimised Truss Models
—
by
This paper presents the analytical optimised truss model based on the principle of the minimum total strain energy theorem. The model was validated against 90 experimental data collected from the literature. The predicted shear strength in the analysis showed a very satisfactory correlation with the test results, with the average experimental/analytical failure load ratio of…

A Study on Effective Strains in Different FRP Shear Strengthening Schemes for Analytical Optimized Truss Models
—
by
This paper presents an optimized truss model based on the principle of minimum total energy theorem. Six most recent effective strain ɛfrp,e models including three design guidelines were selected for the analysis. Three reinforced concrete beams strengthened with different fiber reinforced polymer (FRP) schemes were chosen. Comparing with current design guidelines, the results of these…

Optimized Effective Strain Model for Externally Bonded FRP Shear Strengthened RC Members
—
by
Discrepancies in the current design guidelines on externally bonded FRP shear strengthening for reinforced concrete (RC) structures had initiated this research study. It is generally believed that the erroneous and irrelevant effective FRP strain models adopted in many of the design guidelines, which are derived entirely based on the 45-deg truss analogy, contributes significantly for…
