The Continuous Strength Method – Review and outlook

The Continuous Strength Method (CSM) is a deformation-based approach to the design of structures that enables continuous, rational and accurate allowance for material nonlinearity (i.e. spread plasticity strain hardening). Central method application limits, determined on basis local slenderness full cross-sections, define resistance structural member or system. can be applied formed using different materials (e.g. steel, stainless steel aluminium) manufacturing processes hot-rolled cold-formed) through assignment suitable stress–strain relationships, used steel–concrete composite in fire scenarios. In construction, CSM more rigorous assessment made development strength system taking due account compatibility between constituent materials. enhancements efficiency and, unlike traditional approaches, allows both ductility (which particularly relevant high steel) demands at ultimate limit state. For hand calculations, set straightforward equations have been developed. Recognising increasing importance use advanced analysis GMNIA), recent research, summarised herein, has focussed integration limits into framework by second order inelastic analysis, where benefits become even substantial. This paper provides review background developments CSM, including incorporation standards. Current ongoing research expand scope recommendations future work are also out.
