Abstract. The analysis of experimental-theoretical investigations in the field of design and assessment of the technical state of operating wooden structures is presented. The article consists of the several parts. In them the main problems are formulated and the way of their decisions which are related to the clarification: the classification and combination of loads and actions; the design resistance of the timber and materials on the basis of it; the models of the long-term strength and durability of the timber; the assessment methods of the design resistance values of the wooden structures elements joints; the criteria of the timber long-term strength for the case of the combined stress and criteria of failure under the conditions of combined non-uniform stress; models of the joints compliance; the methods for determination of the strength and elastic characteristics of the timber and materials based on it for operating structures; the assessment methods of the residual life of operating structures are presented. This article formulates the problems and ways of their solution concerning the classification of loads, determination of design values of resistances and long-term strength of wood used when designing structures.
Key words: timber structures, long-term strength, design resistance, load, reliability. - REFERENCES
