METHODS OF JOINERY TIMBER CONSTRUCTION WITH THE CLAW DOWELS
A review of methods for studies of conections of timber structures.Considered the most famous works of the national school of design and foreign regulations. The paper presents the main findings of the work produced by the authors, including dowel type connections, the connection to the punched metal plates, dowels, pins, since these cobections are a kinddowel type connections. The review found that at present there are no methods for the calculation of nodal connections wooden structures to claw washers limit state under the action of the second group of short-term and long-term loads, taking into account the mechanical properties of wood in area of contact with the teeth or pins. The analysis of the state of the question allowed us to formulate the main directions of research, including a program of experimental research.
