    Structural Concrete, 2026
    This paper presents a numerical investigation on the behavior and shear capacity of reinforced concrete (RC) continuous deep beams with and without openings. The numerical model is validated against the experimental results of 10 RC continuous deep beams from the literature. The validated model is then used to conduct an extensive parametric study to investigate the effect of critical design parameters on the behavior and shear capacity of RC continuous deep beams. The examined parameters include concrete compressive strength, shear span to depth ratio, member depth, vertical and skin reinforcement ratio. The numerical results confirm that shear span to depth ratio is the most critical parameter also for continuous deep elements. Furthermore, the strut‐and‐tie provisions of ACI 318‐19 and EC2 are shown to be conservative and provide a non‐uniform margin of safety in predicting the shear capacity of RC continuous deep beams.

  • Numerical Analysis of the Flexural Strength and Ductility of RC Beams Strengthened with Steel-Reinforced Grout (SRG) Composites
    Kamaran S. Ismail
    Polytechnic Journal, 2025
    This research examines the flexural behavior and ductility of reinforced concrete beams strengthened with steel-reinforced grout (SRG) composites using a numerical modeling approach. Experimental results from nine SRG-strengthened beams, as reported in the literature, were used to validate the model. The validated model was applied in a comprehensive parametric study to explore how the number of SRG layers, flexural reinforcement ratio, and SRG end anchorage affect the flexural performance and ductility of the beams. The findings show that SRG provides an effective solution for strengthening under-reinforced beams, notably improving their load-carrying capacity and mid-span deflection. However, the technique has little effect on beams that already possess adequate reinforcement. To further analyze SRG's impact on the flexural capacity of RC beams, the numerical results were compared to predicted strength values obtained through the section analysis method. Both the ACI 549-4R13 and ACI 440.2R-08 design strain models were incorporated in the analysis. The findings revealed that, although ACI 440.2R-08 design strain model was not initially developed for SRG, it yielded more accurate results than ACI 549-4R13. As a result, until more design guidelines are developed, it is recommended to use the ACI 440.2R-08 provisions for predicting the flexural capacity of SRG-strengthened RC beams.

  • Utilization of Carbon Fiber Reinforced Polymer for Strengthening of Structural Light-weight Reinforced Concrete One-way Slabs

    Polytechnic Journal, 2022
    Among many manufacturing industries, civil engineering sectors have been more involved in incorporating fiber reinforced polymer (FRP) composites. These composite materials have been selected as an appropriate solution for strengthening reinforced concrete structural elements because of their excellent tensile strength, high strength to weight ratio, and simplicity of implementation. This experimental study aims to evaluate the flexural behaviors of structural light-weight reinforced concrete (SLWC) one-way slabs strengthened with different patterns of CFRP. The proposed material in the current study is using pumice aggregate as a full replacement of natural coarse aggregate. Four structural light-weight concrete (SLWC) slabs with the dimensions of 1200 mm long, 450 mm wide, and 80 mm thick were cast and tested to failure. One slab has been taken as a control and the other samples are strengthened with five strips in one layer, ten strips in two layers and full wrap CFRP. The samples are tested under a four-point load bending test setup until failure. Each of the ultimate loads, mid-span deflection, cracking loads, crack patterns, and failure modes were well evaluated. The results showed that, strengthening with CFRP composites significantly increases load-carrying capacity. Strengthening with five strips, ten strips, and full wrap with CFRP increased the ultimate capacity by 115%, 138%, and 170% respectively and decreased mid-span deflection by 43%, 58%, and 55% compared to the reference specimen respectively.
  • Shear Strength of Reinforced High-Performance Concrete Wide Beams

    Zanco Journal of Pure and Applied Sciences, 2021
    Wide shallow beams have become more common among structural designers since having more space for utility services under the floor. However, the provisions of codes of practice need to be evaluated against an experimental data to evaluate their margin of safety for this type of structural element. This paper is an experimental and theoretical investigations on the shear behavior and capacity of wide shallow beams. A total of seven beam specimens were tested to assess the effect of beam width to height ratio (b/h) which ranged from 0.67 to 3; shear reinforcement ratio ranging from 0 to 0.222%; and carbon fiber content ranging from 0 to 0.53%. The results show that with increasing width to height ratio, the shear strength of the beam decreased and the provisions of codes of practice (ACI318-14 and EC2) might not lead to accurate results when they are used to predict the shear capacity of wide shallow beams.

    Journal of Structural Engineering United States, 2018
    Strut-and-tie models (STMs) are often used for the design of shear critical deep members because they can rationalize the shear transfer within discontinuous or disturbed regions in reinforced concrete structural elements. Most current codes of practice adopt the strut-and-tie method but provide very little guidance on how to select appropriate strut-and-tie layout and dimensions. Furthermore, the effectiveness factors used to account for the biaxial state of stresses in struts of deep beams are not reliable. This paper reviews the application of STMs for the design of RC deep beams and evaluates current formulations of the effectiveness factor. Experimental and numerical studies are used to assess how the effectiveness factor is influenced by different parameters, including concrete compressive strength, shear span:depth ratio, and shear reinforcement ratio, and to arrive at a more reliable strain-based effectiveness factor. Various effectiveness factors are examined against an extensive database of experimental results on RC deep beams with and without shear reinforcement. The results show that the proposed effectiveness factor yields the most-reliable and most-accurate predictions and can lead to more-economical and safer design guidelines.
