dc.description.abstractБагато будівель та споруд під час експлуатації потребують обстеження, реконструкції або підсилення залізобетонних елементів. Під час реконструкції виникає потреба в наскрізних отворах для прокладання комунікацій та встановлення сучасних інженерних систем. Дослідження показують, що такі отвори загалом знижують міцність залізобетонних елементів. Вплив отворів залежить від їх розташування, розміру та форми: отвори в опорних зонах та зонах стиснення мають найбільш негативний вплив на міцність, тоді як отвори в середині прольоту або нейтральної осі менш шкідливі. Круглі отвори мають менший вплив на напруження, ніж квадратні. Однак досі недостатньо досліджень впливу таких отворів на конструкції, що експлуатуються, що вимагає додаткових досліджень для формулювання чітких рекомендацій та забезпечення надійності будівель у довгостроковій перспективі.
dc.description.abstractBuildings often require inspection or reconstruction of reinforced concrete elements due to new regulations, technical equipment and changes in operating conditions. During reconstruction, there is a need for through openings to lay utilities and install modern engineering systems. Studies show that such openings generally reduce the strength of reinforced concrete elements. The impact of openings depends on their location, size and shape: openings in the support areas and compression zones have the most negative impact on strength, while openings in the middle of the span or neutral axis are less harmful. Round openings have a smaller effect on stresses than square openings. However, there is still insufficient research on the impact of such openings on structures in service, which requires additional research to formulate clear recommendations and ensure the reliability of buildings in the long term.
