... a building’s ability to be extended is limited. To address this, 11 scenarios, each modelling a different source of under-utilisation, were developed and applied in the design and reappraisal of 11 252 hypothetical steel-frame office buildings. An average reserve capacity of 10% was found in optimal Eurocode...

... finite-element modelling steel steel structures structural analysis Due to the inelastic behaviour of structures in design earthquakes, the existence of residual deformations is one of the main issues in the seismic behaviour of steel buildings. To address this issue, the novel idea of self...
