Title: Moment Re-Distribution In Indeterminate RC Beams & Slabs With 500mpa Grade, Class L and Class N Reo.
Appears on pages(s):
Abstract:A computerised method of analysis has been developed to predict the local flexural deformations in a reinforced concrete beam at all stages of loading, from the progressive formation of individual cracks up to failure, either by steel fracture or concrete softening. This paper shows how the local deformation model can be used as the basis for the analysis of the overload behaviour and collapse of continuous beams and slabs. Both ductile and non-ductile members are treated. The paper also discusses design aspects of ductility, and in particular how available and required ductility can be evaluated, and used either to check the adequacy of current AS 3600 ductility design requirements or in a more fundamental and more direct design treatment of moment redistribution. The computational method is being used currently in a study of indeterminate beams and slabs constructed with 500MPa Class L and Class N reinforcing steels. The overall aim of the work is to develop new, more accurate, design clauses for the new 500MPa reinforcing steels.
