Inelastic Behaviour of Three-dimensional Structures Under Concurrent Seismic Excitations
Year: 2025
Type: conference-paper
Abstract: SUMMARY The paper discusses the earthquakes' phenomenon of generating three concurrent orthogonal excitations. The study considered only the two horizontal earthquake radial and tangential components. The SRSS and λ-percent combination methods were investigated for their reliability in the evaluation of the maximum structural response. The results of an extensive elastic and inelastic numerical timehistory study using three-dimensional structures were discussed. These results confirmed that the SRSS and the 30-percent combination methods are inappropriate. The behaviour of the studied inelastic structures was not much different from the elastic structures. The study suggests a 45-percent response combination rule to be used in the elastic and inelastic analyses of structures.
