Error estimation in vibroacoustic problems solved by means of finite elements
(2010-06)
Text en actes de congrés
Accés obertThe vibroacoustic equations can be solved by means of the finite element method. A discretisation of the structure and the acoustic domains is required and highly influences the quality of the numerical solution. There ... -
Evaluation and refinement of closely spaced buildings´performance under near-fault ground motions
(2016-01)
Article
Accés obertThis paper investigates the seismic behaviour of closely spaced fixed-base and isolated building structures in near-fault (NF) zones. Seismic pounding of fixed-base structures is considered at different heights, being from ... -
Experimental and numerical study of Advanced Transfer Path Analysis applied to a box prototype
(2019-01-01)
Article
Accés obertAdvanced Transfer Path Analysis (ATPA) is a technique that allows the characterisation of vibroacoustic systems not only from the point of view of contributions but also topologically by means of the path concept. Some of ... -
