Analysis of Wind Load Effects and Modeling of Equivalent Static Wind Loads of Tall Buildings Based on Synchronous Pressure Measurements

ABSTRACT: The wind load effects of 20and 50-story buildings are analyzed involving higher mode contribution based on wind loads derived from synchronous pressure measurements in a wind tunnel. The variations of gust response factors (GRFs) associated with different responses are studied, revealing the deficiency of the traditional GRF-based equivalent static wind load (ESWL) in current loading code. The comparison of wind load effects with those determined base on ASCE7-05 are also conducted. A practical methodology of modeling ESWLs on tall buildings involving the higher mode contribution is proposed. Finally, the mode shape correction factors required in the high frequency force balance (HFFB) technique are revisited.
