Beam and slab connecting structure for self-restoring structures

Abstract

The invention discloses a beam and slab connecting structure for self-restoring structures. The beam and slab connecting structure comprises a beam and a slab. The beam and the slab are provided with holes whose diameter is larger than that of a screw, so that sliding requirements between the beam and the slab can be met. A gap between the screw and the concrete slab is filled with plastic foam or is foamed, so that vertical sliding is not restricted, the bending moment caused by a gravity load effect at the beam and slab connection can be restricted. When a self-restoring reinforced concrete frame structure employs the beam and slab connecting structure, a floor stretching problem caused by a condition that beam-column joints of the re-storing structure are opened under a seismic force effect can be effectively solved. When a prefabricated type concrete structure employs the beam and slab connecting structure, temperature stress can be effectively released, and the installation and construction can be facilitated. The bending moment caused by the gravity load effect at the beam and slab connection can be effectively restricted through the connecting manner mentioned above. The beam and slab connecting structure is simple, is rapidly constructed, is reasonably forced, and has good technical and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and relates to a beam-slab connection technology applied to a self-resetting structure, in particular to a beam-slab connection structure applied to a self-resetting concrete frame structure with a node opening function. technical background [0002] Recoverable functional structure is a new type of shock-absorbing control structure. It can not only protect people's lives and property during earthquakes, but also help people resume normal production and life as soon as possible after a major earthquake. It is an ideal structure for seismic design. new direction. Restorable structural systems mainly include replaceable structural components, rocking structures, and self-resetting structures. [0003] In recent years, studies have shown that the sway of the structure can reduce the seismic action and the ductility design requirements of the structure itself, reduce the earthquake da...
