To understand the behavior of all beams designed by; a case study we assumed. This case study leads to investigate flexural and shear behavior of reinforced concrete beams. This case study contain 90 beams made of (N.S.C) and (H.S.C) ,with dimension (150*250)mm , clear span 2000mm, length all beams equal 2300mm ,shear span to depth ratio (a/d) ranged from (1 to 2 to 3) , compressive strength concrete (fc) ranged from (30, 60, 75) Mpa, web reinforcement ratio (uv) ranged from (0.14%,0 .28%, 0.25%, 0.50%), and longitudinal reinforcement ratio (u) for reinforced concrete beams ranged from (0.67%, 1.19%, 1.5%, 2.38%, 3.0%). Finite element program 2ANSYS 143 was used to calculate the final straining actions and effect variables on first flexural crack load (pcr), flexural shear crack load (pv), Ultimate failure load (pu), Defflection, tensile and yield stresses for longitudinal reinforcement and web reinforcement , stages for principle stresses and vector mode principle stresses ,and modes of failures for all beams designed
