A NOVEL HYBRID MODEL OF REINFORCED CONCRETE DEEP BEAMS WITH CURVED HYBRIDIZATION

cfrp eeffects on reinforced concrete deep beams

deep beams are type of beams which their behavior is different from conventional beams because of their particular type of geometry. in this paper, the retrofitting of these beams is considered and 10 deep beams are tested experimentally and discussed about retrofitting methods. experimental studies indicate that the use of cfrp bands in the direction perpendicular to diagonal cracks in compari...

Strut Deformation in CFRP-Strengthened Reinforced Concrete Deep Beams

Strut-and-tie model (STM) method evolved as one of the most useful designs for shear critical structures and discontinuity regions (D-regions). It provides widespread applications in the design of deep beams as recommended by many codes. The estimation of bottle-shaped strut dimensions, as a main constituent of STM, is essential in design calculations. The application of carbon fibre reinforced...

Refinement of Strut-and-Tie Model for Reinforced Concrete Deep Beams

Deep beams are commonly used in tall buildings, offshore structures, and foundations. According to many codes and standards, strut-and-tie model (STM) is recommended as a rational approach for deep beam analyses. This research focuses on the STM recommended by ACI 318-11 and AASHTO LRFD and uses experimental results to modify the strut effectiveness factor in STM for reinforced concrete (RC) de...
