Theoretical and experimental analysis of reinforced concrete T-beam before strengthening

pages 25 - 28, full text

The paper deals with numerical analysis and experiment of shear stress and resistance of reinforced concrete beam with T cross-section. The analysis aims to determine the stress level of critical components of the beam before additional strengthening. The determination of reinforcement utilization, angle of shear crack and its development derived from truss models according to Eurocode 2 with using non-linear numerical analysis and experiment. A three-point test with an asymmetrically placed load is analyzed. The specimen is made of reinforced concrete with a length of 4.2 m with a T shape cross-section height of 0.3 m and width 0.4 m. Four beams were experimentally tested, of which reference one was loaded up to failure to obtain the shear resistance of the basic cross-section. The other 3 specimens were loaded until the shear crack appeared. The cracked beams will be further used for research various methods of strengthening reinforced concrete cross-sections in shear.
