    • Due to the lack of design guidelines and specifications for utilizing a beam with a web opening subjected to earthquake loading, the engineers tend to design the web reinforcement in a more conservative manner, leading to higher fabrication costs. Knowing that under seismic loading conditions, some part of the beam at the middle span is subjected to minor loading, thus making it possible to introduce a web opening without any reinforcement. In this study, finite element analysis is utilized to investigate the performance of the beam with one unreinforced large circular web opening subjected to seismic type loading. A reliable material model is proposed to be used in the analysis. As the result of the analytical study, a design guideline to determine where a large circular web opening is permitted to be introduced without any reinforcement is proposed. In addition, for a stricter acceptance criterion, the study of a beam with one large circular web opening reinforced with reinforcement plate around the opening is conducted. The analysis result shows that only a small dimension of the reinforcement plate is needed to maintain the beam performance under seismic load.
