A numerical analysis of the limit state for solids, with an adequately described structural
geometry, is often a computationally demanding task, and there is a need for an effective …

In the field of nonlinear mechanics, many challenging problems (eg, plasticity, contact,
masonry structures, nonlinear membranes) turn out to be expressible as conic programs. In …

The present work addresses the problem of maximizing a structure load-bearing capacity
subject to given material strength properties and a material volume constraint. This problem …

Several examples of structures have been severely damaged, or even reached the total
collapse, after the propagation of some local failure, resulting from an accidental or …

We investigate the use of a second-order cone programming (SOCP) framework for
computing complex 3D steel assemblies in the context of elastoplasticity and limit analysis …

The present manuscript presents a framework for automating the formulation and resolution
of limit analysis problems in a very general manner. This framework relies on FEniCS …

Masonry walls are typically subjected to eccentric compressive loadings in common
buildings. However, the design of walls towards this type of solicitation remains very …

Limit analysis (LA) is successfully used for investigating the bearing capacity of reinforced
concrete (RC) structures. Some cautions must be taken when using this method for RC since …

This paper introduces a 3D equilibrium-based finite element formulation for reinforced
concrete. The stress unknowns in the proposed formulation strongly satisfy the equilibrium …

Complex triaxial stress states are present in many reinforced concrete structures. These
structures are often analyzed using simple hand calculations based on methods designed …
