DUCTILITY REQUIREMENTS FOR CONTINUOUS REINFORCED CONCRETE STRUCTURES

An incremental method of analysis is used in conjunction with a section analysis program to study the overload, collapse and post-collapse behaviour of continuous reinforced concrete beams with limited ductility. A flexibility type approach is adopted, which is efficient and fast for the specific structure considered. The method gives results which are in reasonable agreement with results obtained from a more general stiffness based method. Numerical studies are used to evaluate minimum ductility requirements which are consistent with currently used methods of ultimate strength analysis and design. It is found that the ductility provisions in both the current reinforced concrete structures code, as 1480, and in the new draft unified concrete code are likely to be unconservative in a number of realistic design situations.
