A simulation study of the effect of shear stresses in non-reinforced and reinforced structures was carried in this work. Using the Finite Element Method and equations of elasticity, columns and concrete deck of a simple storey structure were subjected to plane strain conditions. The results showed that proper reinforcement causes stresses to be directed into the reinforcements with the resultant shear stresses in the steel reinforcements far below the yield stresses of the steels. In non-reinforced and insufficiently reinforced members it was observed that stresses were directed into the concrete itself with resultant transverse shear at critical joints of the structure. In the insufficiently reinforced member, the resultant shear of the concrete resulted in load transferred to the reinforcement itself with the resultant buckling of reinforcement and eventual collapse of structure.
