Abstract

The reliability of a reinforced concrete beam with respect to the limit state of crack width under monotonically increasing short-time loading conditions is estimated using the Monte Carlo technique and failure rate analysis. Using both methods the reliabilities of 24 beams whose test results are available in the literature and three beams tested in the laboratory have been determined for a limiting crack width of 0.2 mm. A comparison of the reliabilities obtained using failure rate analysis with those obtained directly from Monte Carlo simulation shows good agreement. From failure rate analysis it is found that a two-parameter Weibull distribution can be used to describe the failure life of a reinforced concrete beam with respect to the limit state of crack width. The mean moment to failure of each beam determined from failure rate analysis is compared with the experimental moment to failure.
