Abstract: The limit analysis of stability problems in geomechanics is formulated as a pair of primal‐dual linear programs that encode, respectively, the kinematic and static limit theorems in a discrete version. The failure surface ...

Abstract: The limit analysis for stability problems in geomechanics can be formulated as a pair of primal‐dual linear programs. This formulation provides a solution that is both kinematically and statically admissible for a discretized ...

Abstract: The well‐known formulation of the optimal design of plastic frames presupposes that all the relevant data are known deterministically. It is realistic to recognize that more usually this information is known only imprecisely. ...

Abstract: This paper presents a new method for the analysis of frames taking into account the distributed plasticity of material. The flexibility method is adopted in the formulation. Under the holonomic assumption for the ...

Abstract: A submarine pipeline is idealized as a linearly elastic continuous beam subjected to vertical loads, and supported on a discretized frictionless seafloor profile. The structural analysis of this beam is considered as a ...

Abstract: This paper presents a numerical method, based on a simple transformation concept, for analyzing the failure loads of slender reinforced concrete columns under uniaxial bending. Both material and geometric nonlinearities ...
