Reliability evaluation of strengthened reinforced concrete members

Abstract

This paper is devoted to a brief analytical overview of study a problem of reliability evaluation of strengthened reinforced concrete (RC) members. The question of definition of real level of strengthened RC members, that are in use, are considered. The effect of external strengthening composite materials (FRP and CFRP strips) on reliability of RC members is presented, considering the statistical character of the design variables (geometry, material properties etc.). The probabilistic calculations, that are considered in this paper, are based on the Monte Carlo method. The importance of determination of reliability indexes of strengthened RC members is presented in the conclusions.
