Experimental and Theoretical Investigation of Wooden Construction Elements’ Connections on Dowel Plates

Abstract

Improvement of dowel joints in order to increase their load-carrying capacity and reliability at the present time remains actual one. A special place among them is occupied by connections with the use of dowel plates. In order to increase the bearing capacity of metal nailed plates developed in NGASU (Sibstrin) with the use of reinforced dowel it is suggested to strengthen the nailed plates in metal plates by means of tight installation on the last metal stamped gear washers. In order to determine the strength and deformability of the developed connections they were prepared and tested under the action of short-term loads along and across the fibers. On the basis of the received data the analysis of short-term bearing capacity and deformability of the offered joints has been carried out. The method of calculation of such connections on limiting states of the first group is offered. The interaction of the limiting load-carrying capacities obtained on the basis of the proposed method with the results of short load action tests of the compounds under consideration was performed.
