Vibration Model Considering Interaction between Ceiling System and Equipment Part Ⅰ: Test and FEM

摘要

(1) In the tests, the vibration frequencies of the integratedceiling system increased drastically after installing theceiling panels.(2) The multilinear link elements were proposed to model theconnection between the ceiling panel and equipment withfriction.(3) The modal properties of the integrated ceiling system andeach equipment in the system were influenced largely by thelink and boundary properties. These properties should becarefully modeled to predict damage in earthquake events.
