ABSTRACT
Problem statement. The problems of long-term deformation of normal and pre-stressed glass fibre reinforced polymer concrete structures are considered on the basis of stress-time analogy.Results and conclusions. Creep coefficient is obtained with the use of creep curve differentiation method. This coefficient forms the basis of analysis of beam deflection under long-term loading. The duration factors obtained are in acceptable parametric ranges. This fact confirms the feasibility of new stress-time analogy method for deformation analysis of normal and pre-stressed glass fibre reinforced polymer concrete structures.
