Abstract

The lack of standardization in vibration mode results has constituted the main shortcoming of operational modal analysis, subsequently resolved by means of the mass modification method. This is a major drawback for civil works, as it interrupts traffic on site, significantly increasing [...]

Abstract

The consideration of the assumption of viscous damping as a starting hypothesis in the dynamic analysis of structures can introduce a substantial error in the calculations. This is due to the energy dissipated [...]
