A new methodology based on the results of wind tunnel tests was proposed in order to obtain the wind-induced responses and equivalent static wind loads (ESWLs) of a highrise building which has complicated shape and is under the aerodynamic interference of other buildings.  The resultant forces on layers of the high-rise building were calculated based on the wind pressures measured simultaneously from wind tunnel tests. Based on the simplified layer model, a methodology to obtain the wind-induced responses and ESWLs accounting for different responses was developed in the frequency domain. Then the developed methodology was applied to a high-rise building to show how it works. Results show that the displacements of the building are contributed mainly by the first vibrating mode, whereas the accelerations are contributed by first several vibrating modes. The displacements and accelerations calculated in the frequency domain match well with those calculated in the time domain. Three ESWLs accounting for the displacement on the top of the building, the base shear and the base moment are almost the same for this building. The accumulated value of ESWLs can be used to determine the most unfavorable wind direction.
