Abstract:
With discussion by Peter R. Barnard, HerbertlA. Sawyer,,M.Z. Cohn, and Emilio Rosenblueth and Roger Diaz de Cossio. Failure due to crushing is a case of instability. The traditional nonlinear moment-curvature approach does not hold for systems exhibiting descending (unstable) portions in their force-deformation characteristics. A method based on a moment-rotation approach and an assumed contaminated zone is presented, which takes into account descending branches.
