Abstract: The object of this study is a castellated beam, in which the large openings in the web have the shape of a regular hexagon. The beam is investigated for the purpose of assessing deflections. Based on a set of experimental studies, the features of the stress-strain state of castellated beams have been defined. The need to take into account the increased deflections of castellated beams due to the openings in the beam web when calculating the deflections of castellated beams at the serviceability limit state verifications has been determined. A comparative analysis of the deflections obtained as a result of the numerical experiment with the deflections of beams determined using the design code technique has been performed. It was established that for verifications of castellated beams at the serviceability limit state, the error in assessing the deflections of a single-span hinged beam loaded with a uniformly distributed transverse load in some cases reaches 20 %. Recommendations have been devised for estimating deflections of castellated beams. According to the proposed recommendations, the error in estimating castellated beam deflections does not exceed 3 % for the range of the beam span to the total height of its cross-section 8.5
