Collapse behaviour of steel columns in fire.
… project is a purely numerical analysis of the inelastic behaviour of steel columns in fire. This is made up of three main parts, each devoted to the development and use of a numerical technique to study the behaviour of steel columns in fire. The first two chapters report on the state of the …

AN EQUIVALENT NON-UNIFORM INELASTIC BEAM-LIKE MODEL FOR THE SEISMIC VULNERABILITY ASSESSMENT OF BUILDINGS
… for both the evaluation of the elastic and the inelastic behaviour of buildings using different calibrations of the equivalent beam-like model characterised by linear or non-linear constitutive laws. Numerical results of two benchmark buildings show the comparisons with the results provided by …

BEHAVIOUR AND STRENGTH OF PLATE TRUNNIONS SUBJECTED TO SHEAR LOADING
… models were able to predict the elastic and inelastic behaviour of the trunnion brace. A shear strength design equation was proposed based on the numerical and experimental results obtained.

Finite deformation of particulate geomaterials: frictional and anisotropic Critical State elasto-plasticity
… structures undergoing geometrically non-linear behaviour. The Mohr-Coulomb and modified Cam-clay constitutive models have both been examined and extended to provide greater realism. Findings from this thesis will interest engineers working in numerical methods in solid mechanics, along with …

Behaviour and modelling of the inelastic response of concrete and steel-concrete infrastructures subjected to low-cycle fatigue
… a fundamental issue. In order to investigate the behaviour of infrastructures under different loads, such as gravity, seismic phenomena, thermal differences, and so on, appears essential a comprehensive experimental campaign on scaled and full-scale specimens. In particular, in order to guarantee …

AN INCREMENTAL MODEL IS PROPOSED FOR THE NONLINEAR RELATIONSHIP BETWEEN THE NORMAL ACTION EFFECTS N, MY AND MZ, AND THE CORRESPONDING CROSS-SECTIONAL DEFORMATIONS, EO, ΦΥ, AND ΦΖ, OF RECTANGULAR REINFORCED CONCRRETE CROSS-SECTIONS. THE INCREMENTAL RELATIONSHIP IS OF THE BOUNDING SURFACE PLASTICITY …
