Non-linear finite element analysis of reinforced concrete: at the crossroads?

This article takes a critical look at the relevance and value of non-linear finite element procedures for analysis and design of reinforced concrete structures. Their potential usefulness as a practical design office tool is illustrated through a sample application. Then, in examining the results of recent prediction competitions, the accuracy of such analysis procedures is examined. Reasons for caution when applying non-linear analysis methods are identified and discussed. Finally, the results of a test programme involving shear critical beams are presented in support of the contention that the behaviour of reinforced concrete is still not always well understood; the test results provide a challenge for validating current procedures.
