STRENGTHENING TECHNOLOGY OF TIMBER TRUSSES BY PATCH PLATES WITH TOOTHED-PLATE CONNECTORS

Abstract

Most textile buildings, erected at the beginning of the XX century, have roofs with timber trusses. The trusses damage after continuous operation, the increased load on the bottom chord and others make it necessary to strengthen tensile members of the trusses. It is proposed to strengthen the tensile trusses members with the help of toothed-plate connectors. They are the shear elements involving the patch plates in structure performance. The paper has the results of shear tests of the wooden samples connected by toothed-plate connectors with post-clamping. The load-carrying capacity of the connection was determined. These results formed the basis for the strengthening technology of tensile elements of segmental trusses by wooden patch plates with toothed-plate connectors. The proposed method of strengthening was applied in Arkhangelsk facilities.
