ANALYSIS OF DEFLECTION MODE OF GLASS REINFORCED PLASTIC POLYMER CONCRETE STRUCTURES UNDER LONG-TERM LOADING

Problem statement. The questions of long-term deformation of usual and pre-stressed glass-reinforced plastic polymer concrete structures are considered on the basis of stress-time analogy. Results and conclusions. Creep factor is obtained with the use of creep curve differentiation method. This factor forms the basis of calculation 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 usual and pre-stressed glass-reinforced plastic polymer concrete structures.
