✦ Synopsis

Probability of Failure Concrete Beams

Paper presents prediction of probability of failure of pre.stressed concrete beams. Probable strengths of basic materials used in the beam are g~enerated as random z,ariables sub/ect to code spec(tfcations and the probability qf failure of the beam is obtained through explicit fi)rmulation. Probability qf.faihlre of beams designed by Indian code of practice and code of American Concrete Institute is illustrated through a set of examples. It is found that the probability q/failure q/'a prestressed concrete beam is very sensitit'e to rariation of steel and less sensitive to the variation in the strength q/'concrete.
