The compatibility of deformation of the hollow-core slab with beams

Abstract

Рассмотрены особенности деформирования узлового шпоночного сопряжения пустотной плиты перекрытия со сборно-монолитным (монолитным) ригелем каркасной конструктивной системы, применяемой для возведения многих зданий, в том числе зданий серии Saret. Выполнены экспериментальные исследования, а также проведены численные исследования напряжённо-деформированного состояния узла сопряжения плиты и ригеля сборно-монолитного каркаса. На основании полученных данных выполнен сопоставительный анализ результатов численных исследований с экспериментальными данными, который показал удовлетворительную сходимость результатов. В результате проведённых исследований получены новые данные касающиеся конструктивных особенностей стыкового соединения пустотной плиты с ригелем. Даны заключения о несущей способности, жёсткости и трещиностойкости конструктивного решения узла сопряжения. Обозначены «слабые места» связанные с проектированием и эксплуатацией узлового соединения плиты с ригелем. Предложены технические решения по устранению выявленных недостатков, такие как установка в пустотной плите верхней арматуры в продольном и поперечном направлениях или исключение шпоночного жёсткого соединения, позволяющие повысить конструктивную надёжность здания.

The features of deformation of the key joint of a hollow core slab with precast-monolithic (monolithic) beam of a frame constructive system, including the Saret series. Experimental studies have been performed and numerical research of the stress-strain state of the slab and beam precast monolithic frame joint are carried out. Based on the obtained data, a comparative analysis of the results of numerical studies with experimental research has been performed, which showed a satisfactory convergence of results. As a result of the conducted researches new data concerning design features of the joint of the hollow slab with the beam have been obtained. Conclusions are given about the bearing capacity, stiffness and crack resistance of the structural solution of the joint node. The “weak points” associated with the design and operation of the joint of the slab with the beam are indicated. Technical solutions have been proposed to address the identified shortcomings, such as installation of the upper reinforcement in the hollow plate in longitudinal and transverse directions or exclusion of the key rigid joint to improve the structural reliability of the building.
