Steel design by advanced analysis: material modeling and strain limits. Journal of Constructional Steel Research, 168, 105980. Structural steel design using second-order inelastic analysis with strain limits. force and moment redistribution) is captured by the strain limit, which is determined based on the cross-section slenderness from the continuous strength method. Further details can be found in the following papers.įieber, A., Gardner, L. In this fashion, the spread of plasticity both within cross-sections and throughout the structure (i.e. In this approach, cross-section classification is eliminated and design is based on beam element geometrically and materially nonlinear analysis with imperfections (GMNIA), utilising strain limits to mimic local buckling. These are summarised belowĭesign by advanced analysis with strain limits Two alternative approaches that utilise advanced structural analysis and streamline the design process into a single step and avoid the need for individual member checks have been developed within the Steel Structures Research Group. Firstly, a structural analysis is performed to determine the internal forces and moments and secondly, design checks are conducted on the individual elements that constitute the structure. Structural design is typically performed using a two step process. Advanced analysis and design of structures
