Popis: Castellated beams are made from a hot rolled steel I-section in a few steps. Firstly, the web of the parent I-section is cut in a particular zigzag pattern and the two halves are reconnected by welding to form a castellated beam with hexagonal openings. In other cases, a spacer plate is placed between the two halves to produce octagonal openings, which increase the section depth. Increasing the depth by adding spacer plates leads to web-post buckling. This study focuses on improving the castellated beam to obtain high strength with relatively low cost by placing a steel ring inside the octagonal openings to strengthen the weakest part, which is its web. The results show that the steel ring is effective in strengthening the web-post.
