(54) MULTILEVEL SEISMIC RESISTANT BUILDING

one

The invention relates to the construction and can be used in the construction of multi-storey buildings.

Seismic resistant multi-storey buildings with carriers of stiffness are known, operating mainly for the perception of horizontal forces 1.

However, this structure has insufficient rigidity and is difficult to manufacture.

The closest technical solution to the invention is a multi-storey earthquake-resistant building with a core of rigidity consisting of prefabricated elements with monolithic inclusions at the junction of the wall panels of the core between them and the ceiling panels with the core of rigidity 2.

The disadvantage of this technical solution is greater labor intensity. In addition, the vertical mating of the wall panels of the core has a complex arrangement of assemblies in which welding work is required for the docking of reinforcing bars, which is undesirable in places of concentration of stresses that perceive dynamic effects.

2

The purpose of the invention is to increase the carrying capacity and rigidity, the degree of resistance to horizontal and torsional loads and increase the number of floors.

This is achieved by the fact that in a multi-storey earthquake-resistant building, including precast stiffening cores from layers, their wall panels and slabs connected to it, the supporting wall panels of the core of rigidity are made with horizontal channels located along their upper ends, and two sides of the panels, with prestressed steel cables placed in the vertical and horizontal channels.

In addition, the core of rigidity can be performed with the protruding sides of the contour forming the outer corners.

FIG. Figure 1 shows the core of rigidity in the level of reinforcement with a horizontal prestressed reinforcement, a horizontal section; in fig. 2 - core of stiffness with distribution of vertical open channels and vertical prestressed reinforcement, horizontal section; in fig. 3; section A-A of FIG. one.

The stiffening core consists of vertical building elements in the form of load-bearing wall panels 1 and 2, which have openings for the side and upper edges of the flange for laying the horizontal tension reinforcement 3 and the vertical tension reinforcement 4.

Slab plates are supported on cores of rigidity 5.

In order to increase the rigidity of the cross section, the core stiffness can be performed with the sides 6 protruding beyond its contour, forming the outward angles 7.

The openings in the core of stiffness are arranged depending on the conditions of the layout on any side of the DRAWING BAR, but it is more expedient to make them run across the floor (see Fig. 3).

The use of this structural solution makes it possible to reduce the metal consumption due to the use of high-strength steel working armature, to improve the quality of manufacture of its component parts under factory conditions to exclude a significant part of the welding work associated with high labor costs and less reliable in terms of the perception of dynamic loads.
