Abstract

The invention relates to a seismic-resistant frame connection. The purpose of the invention is to reduce seismic effects on the frame. Parallel-shaped pair disks are rigidly connected to the columns and crossbars of the frame cell. In the diagonal gaps between the disks, there are damper-shaped steel tape between the disks, in the center of the cell there is an elliptical stripping damper. All dampers are attached to the disks with anchor bolts 1 of 3 p f-crystals. 3 silt

The twin 1-packs are attached to the columns 3 and to the rige gm 4 with a rigidly full face with the formation of gaps diagonally placed in the cell1 2 gaps 5 between the eyes of the displaced Isks 1 and the gap h between them with 1 vertices 7 that have curved linear shapes for example parabolic

The link is equipped with the hip of the frame 8 9 in the form of an effective agent. The damper 8 has the shape of -p gypsum, the dark is in the center of the cell 2 and the curvature vertices 7 are vice 1

Dampers 9 have syn-shaped forms and are located in a shackle of tyg gaps 5

Dampers 8. 9 have oval holes 10 and are attached to disks 1 by means of anchor bolts 11, embedded in disks I and inserted into oval slots 10 of dampers 8, 9 and between fixed nuts 12

Between the disks 1 and the tempers 9, elastic control products should be placed

The disks 1 can be made in the above single element with columns 6 and bolts. The connection is mounted in the following order. The concrete disks 1 are attached to the skeleton of the skeleton with gochons 3 and crossbars 4. Then they are inserted into the gaps 5, 6 between the disks 1 Dampers 8. 9 with bolts 1 1 inserts 1 in the slot 10 Tempfers 8, 9, which are made on one side of each damper 8, 9

Between the discs 1 and the dampers 8, 9, the elastoplastic gaskets 13 are left, they can be inserted before mounting the dampers 8. For example, they can be stuck

Under the seismic action, horizontally from left to right on cell 2, the left and right extreme disks 1 will experience compressive forces. The dampers 8 will compress and the damper 9 will work in compression and bending. The upper and lower disks 1 will experience eccentric compression.

When seismically acting on the cell 2 from left to right at an angle (up), the leftmost disk 1 will work in compression, the left upper and lower dampers 8 will experience compressive force. The damper 9 works in compression and bending, the right upper and lower dampers 8 will compress, the lower disk 1 will work on bending, the right extreme disk 1 will bend, the top disk 1 will experience eccentric compression

Under the action of the seismic action from right to left on the cell 2, the operation of the communication elements changes to the opposite of the above described

In this case, the dampers 8, 9 will absorb seismic energy

Thus, the design of the communication allows to perceive not only tensile, but also compressive forces, which makes it possible to significantly reduce the seismic effect

effect on the frame of the building by the use of dispersed dampers.
