DEVELOPMENT OF MULTI-DEGREE-OF-FREEDOM AEROELASTIC MODEL AND EVALUATION OF WIND RESPONSE OF A HIGH-RISE BUILDING

Abstract

This study is divided into two steps. In the first step, a multi-degree-of -freedom aeroerastic model is developed. With this model, the eccentric distrance, the frequency ratio of a torsional mode vibration to sway mode vibration, and the structural damping can be easily chaned. In the second step, displacements obtained from the "multi-degree-of -freedom aeroelasic model" test are compared with displacements estimated from wind forces obtained from a dynamic force balance model and displacement obtained from a "stick model" test. These comparisons verify the validity of each model test.
