Abstract
This research is devoted to investigating the experimental and theoretical behavior of deep beams was done to study the effect of using reinforcement with high tensile strength
from (GFRP) glass fiber reinforcing polymer bars in (HSC) high strength deep beam with different ratios of reinforcement and concrete compressive strength. All beams have the same dimension of (1500mm length, 150mm width, and 500mm height).
The experimental program includes manufacturing the GFRP bars and casting and testing of eight specimens. two of them were tested as control beams with steel bars reinforcement and the others were GFRP bars reinforcement.
The variables include the type of concrete and reinforcement ratio, crack pattern pf GFRP deep beams under the influence loads, load- midspan deflection behavior, strain in
concrete, crack width and their failure mode where discussed.
Non-Linear finite element analysis (NLFEA) using ANSYS 19.0-R2019 to verify the experimental results.
The results of load-deflection and initial cracks of concrete members were discussed. The structural behavior of testing deep beams was upheld by the theoretical developing
FE models utilize the software ANSYS 2019 R1 program. There was good agreement between the experimental and analytical analysis. GFRP reinfor ced concrete design is governed by serviceability limits and load-deflection mid-span and strain of GFRP and steel bars and concrete were observed. deep beams was done to study the effect of using reinforcement with high tensile strength from (GFRP) glass fiber reinforcing polymer bars in (HSC) high strength deep beam with different ratios of reinforcement and concrete compressive strength.
