Abstract:
Based on the results of synchronous dynamic pressure wind tunnel test of rigid model, the wind load of Guangzhou Songri Headquarters Building was researched in frequency domain by the way of facade wind pressure integration. The results show that cross wind vibration of floors keeps more consistently than that of downwind direction; proportions of downwind and cross wind base moment components vary with different wind direction angles and the form of a building facade; the peak accelerations of top floor in this building can meet the comfort requirements in the code. The sensitivity analysis of equivalent static wind load and peak acceleration provide guidance for the structural optimization design.
