in places that There is no access to the profiles or cross sections Rolled steel deep, The use of castellation beam at structural steel is suitable and useful. The main advantage of using these beams compared to conventional beam, increase the modulus of inertia torque level, Without increas weight, Another advantage ability to pass electrical and mechanical equipment from between beam holes, the result is that reducing the height floor to floor. In the study of castellation beams using finite element method using ANSYS investigated, and finally between the beams reviews, castellation beam with welded plates (octagonal holes) the least deflection is showing continuing with the study of types stiffener structure of castellation beam, this result was achieved, the use of stiffener structure Around the hole along with rectangular plates welded, is least deflection
