웨브에 개구부가 있는 대형 철골 모멘트골조의 유한요소해석

다국어 초록 (Multilingual Abstract)

The purpose of this study is to evaluate the structural performance of beam-column steel connections in deep beams with different beam depths and web through modeling through finite element analysis (FEA). The overall hysteresis curves and buckling shape were deemed to be similar. For webs with openings, we confirmed that stress was concentrated around the opening of the web, and we observed the deformation of the flange and the web at that point. The beam model with a rectangular web opening showed the highest equivalent plastic strain (PEEQ) values at the end of the beam, whereas the one with a circular opening showed the highest PEEQ values around the web opening. All samples satisfied the performance requirements outlined by Korea Design Standard (KDS) and Special Moment Frame (SMF). In addition, creating plastic hinges through web openings was deemed suitable.
