title = "Unified Finite Element Limit Analysis for reinforced concrete",
abstract = "This Limit analysis has for many years proven to be a strong design tool for the ultimate strength of reinforced concrete structures. Numerical solutions for the ultimate limit state of reinforced concrete structures, also known as Finite Element Limit Analysis (FELA), have often been based on the lower bound method requiring a nodal setup far from the standard Finite Element Method (FEM) and with issues regarding the kinematic interpretation. Recently a unified weak formulation of FELA with identical lower and upper bound solutions has been presented. This formulation has a standard FEM nodal setup and a clear kinematic solution. Here this unified formulation is extended to solid reinforced concrete structures. The modelling tool is validated through a classical 2D solution for a deep beam, and it is exemplified for the classical Fox plate. The solid modelling of the plate structure exemplifies that solid FELA modelling of reinforced concrete structures with complex stress states may often reveal a significant extra load bearing capacity.",
