Abstract: Field measurement data are base of the research of wind-resistance on structures. Based on the wind-induced displacement response from field measurement on Jin Mao Tower under the Typhoon Matsa, 2005, the corresponding equivalent static wind loads of Typhoon Matsa were predicted from the calculation model. These results were compared with ESWL from wind tunnel tests. Some parameters such as wind profile, damping ratio were discussed in order to check the reasonableness of wind parameters in the designing Jin Mao Tower.
Keywords: field measurement; wind-induced response; equivalent static wind load; high-rise building; damping ratio
