The Recommendation for Loads on Building (RLB) of AIJ allows for a simple calculation of wind response parameters without using time history analysis. The RLB also considers the simultaneity of wind forces and stipulates a method for combined of wind loads. However, there are a few cases in which the wind force of a seismic isolation layer under combined loads has been evaluated. Therefore, this study evaluates the combined wind loads based on the RLB for high-rise seismically isolated buildings with elastic sliding bearings.
