Dynamic Characteristics Test and Analysis of Long-Span Cantilevered Floor Systems in Shenyang Culture & Art Center
2014
For floor serviceability, stiffness and resonance are dominant consideration in the design of long-span floor systems or large-cantilever floor systems, which usually have lower stiffness and smaller dampings. In this paper, a dynamic characteristics test of long-span cantilevered floor systems in Shenyang Culture & Art Center was performed by using pulsating methods to determine the natural frequencis and the dampings, which were compared with those from the numerical modal analysis based on the Midas/gen platform. The research provides a basis for a further study of floor vibrations due to human comfort.
