PREDICTION OF COMBINED WIND LOADS USING THE SPECTRAL MODAL METHOD FOR ELASTIC RESPONSE OF A HIGH-RISE SEISMICALLY ISOLATED BUILDING WITH ELASTIC SLIDING BEARINGS

In the Guidelines for Wind-Resistant Design of Base-Isolated Buildings, the rank of the seismic isolation layer is evaluated using the combined of wind loads. In particular, when the seismic isolation layer behaves elastically against the wind load, the wind response can be calculated using The Recommendation for Loads on Building (RLB). RLB uses a method to evaluate wind loads based on the spectral modal method by setting modal parameters, but the setting method is unclear. Therefore, this study sets modal parameters for a super-high-rise base-isolated building and evaluate the combined of wind loads calculated using the spectral modal method.
