Numerical Study on Dynamic Behavior of Glass Screen Based on Out-of-Plane of Low-rise Steel Frame Building Based on Seismic Observation Records

Abstract

Serious damage to nonstructural components such as window glass and suspended ceiling was reported after the 2011 earthquake off the Pacific coast of Tohoku. Strong-motion earthquake measurement was conducted at a low-rise steel-frame building with glass screens to examine its vibration characteristics that could generate force on the glass screens. From the analysis and an earthquake observation done, it was confirmed that the Glass Screen at the end of the building tends to be easily destroyed due to the influence of coupling with the torsional vibrations in addition to the large vibrations in out-of-plane direction.
