Ductility of high strength concrete in bending with or without confinement



One of the important principals of RC structural design in earthquake regions is ductility considerations, which need a different design approach. In this paper, the parameters affecting high strength concrete HSC are considered and the tools (tables and curves) are prepared for ductile design of reinforced HSC bending sections. Using these tools, it is possible to easily and safely design for ductility of singly and doubly reinforced flexural confined and unconfined HSC sections. The worked examples are also presented
