Review article

The article presents the results of numerical and experimental study of plug-in joints of columns and slabs in prefabricated reinforced concrete frame buildings. The feature of such joints is five elements participating in the work - two abutting ends of the columns, a slab and two mortar joints. A method for calculating the axial and shear deformability of these joints has been developed for the first time. It makes possible to estimate the horizontal and vertical displacements of the frame.
