The contemporary precast-cast-in-place housing construction has become widely used on the territory of Russia. A great amount of big construction companies begin using the technology of precast and cast-in-place housing construction as the main one. This fact is proving the convenience of reinforced precast and cast-in-place concrete for the buildings of various functions in the climatic conditions of our country. Though there is a lack of investigations of such constructions though they are increasingly developing. Due to the lack of experimental research data existing at the moment, which allow estimating deformed condition of precast-cast-in-place constructions of slabs objectively, experimental research of hollow slab longitudinal beam with precast-cast-in-place and cast-in-place joist was carried out by the authors. The results of the given work prove the data previously obtained by the authors in their experiments using a fragment of precast-cast-in-place slab.

Приведены результаты экспериментальных исследований узла сопряжения пустотной плиты со сборно-монолитным и монолитным ригелем, проведенных авторами. Результаты исследований позволяют устранить существующие на сегодняшний момент недостатки экспериментальных данных, не позволяющие объективно оценить деформированное состояние сборно-монолитных конструкций перекрытия.
