Title: Initial distortions in supports of continuous beams as an alternative to the plastic redistribution of moments
Author(s): A. Garstecki, J. Ścigałło
Appears on pages(s): 249-261
Abstract:In the present paper it is assumed that initial distortions are introduced in the form of rotational clearances within the beam at the cross sections at the supports or in the form of gaps between the beam and the supports. Properly scaled distortions can result in the redistribution of bending moment similar to the plastic redistribution. The redistribution induced by initial distortions is not limited by the plastic rotational capacity. In the paper the method is discussed for both, linear and nonlinear moment-curvature relations. Numerical examples of continuous RC beams illustrate the theory.
