Development of a Baseline Digital Twin Model as a Prerequisite for the Digital Twin Definition of a PSC-I Bridge with Model Updating Considering Member Stiffness

Buildings
Structural health monitoring using various sensors has been widely employed to assess the structural conditions of bridges. In addition, the concept of a digital twin was introduced, which encompasses the life cycle information of a bridge and its real ...

Animal models of tumorigenic herpesviruses — an update [PDF]

Current Opinion in Virology, 2015
Any one model system, be it culture or animal, only recapitulates one aspect of the viral life cycle in the human host. By providing recent examples of animal models for Epstein Barr Virus and Kaposi Sarcoma-associated Herpesvirus, we would argue that multiple animal models are needed to gain a comprehensive understanding of the pathogenesis associated

Dynamic characterization of progressively damaged segmental masonry arches with one settled support: experimental and numerical analyses

Fracture and Structural Integrity, 2020
This paper aims to explore the dynamic behavior of a segmental masonry arch subjected to increasing horizontal displacements of one support. To this end, output-only dynamic identification techniques are first used to track the evolution of the dynamic ...

Evaluation of Behavior of a Ball Joint System in a Double Layer Grid through Updating of its Natural Frequencies [PDF]

مجله مدل سازی در مهندسی, 2010
Due to the some uncertainties during manufacture and assembly of double layer grids with ball joint system, the behavior of this jointing system in the structure is different from the behavior of individual and discrete joints.
