Evaluation of residual deflections of partially prestressed beams after low-cycle impacts
Incoming article date: 20.12.2019Operational characteristics of reinforced concrete bending elements under low-cycle impact are considered. The residual deformations and deflections of partially prestressed structures exposed to repeated static loads are investigated, the dependences for estimating the residual deformations and deflections of partially prestressed structures under the action of low-cycle loads are Given. On the basis of the analysis, the dependence of the relative increase in deflections on the coefficient of partial prestressing with repeated application of static loads was established.
Keywords: partially prestressed elements, repeated loads, residual deformations, non-stressed reinforcement, low-cycle impact, residual deformations and deflections
