Abstract

The invention relates to metal frames of one-story earthquake-resistant industrial buildings. The aim of the invention is to increase the seismic stability of the frame by limiting the deformation parameters to an acceptable limit. Elastic rods are missed in the holes of the flanges installed on the ends of the lower part of the trusses, and in the holes of the shelves of the columns and equipped with stop nuts on the ends. Between the last and the shelves of the columns formed gaps, fixed by washers of easily crushed material. Dampers in the form of cup springs are installed between washers and column shelves on elastic rods. The size of the gap is determined from the specified ratio. 1 hp f-ly, 11 ill.
