Flexural impact resistance of steel beams with rectangular web openings

This paper focuses on the flexural impact behaviour of steel I-beams with rectangular web openings. Published studies resistance and design requirements perforated beams are limited. To shed light such a topic, detailed non-linear three-dimensional finite element models (FEMs) were developed using ABAQUS. Rigorous validation process was employed to verify FEMs built against published experimental tests in terms force displacement time histories. Reasonably good agreement obtained between numerical results corresponding ones. Then, validated exploited investigate The factors examined current study area, depth, number reinforcement openings under different velocities ranged 2.214–7 m/s provide comprehensive understanding response It observed that increasing narrow negligibly effected beams. Moreover, wide significantly reduced dynamic Besides, slight effect mid-span deflections if depth increased. considerable improvement by providing horizontal particularly for those showed similar mode failure generating four plastic hinges around edges an opening, which is produced quasi-static loading.
