A critical look is taken at the state-of-the-art in nonlinear finite element analysis of reinforced concrete structures. In examining the results of recent prediction competitions, the accuracy of such analysis procedures is gauged. Reasons for caution when applying nonlinear analysis methods are then identified and discussed. Finally, the results of a test program involving shear critical beams are presented in support of the contention that the behaviour of reinforced concrete is still not well understood. The tests represent a good challenge for validating current procedures.
