Wind-induced pressures acting on the Wind Engineering Research Field Laboratory
(WERFL) of Texas Tech University are integrated over each surface to obtain three
forces and moments at the base of the building along the three principal axes with its
origin at the geometric center of the building. Mean and fluctuating pressure
distributions around the WERFL building are investigated, and the pressure
distributions producing maximum fluctuating along-wind loading, across-wind
loading, and torsional moment are studied, and the correlation between these forces is
studied, a method to investigate the load combination of these forces is proposed.
WERFL building is also used for estimation of wind loading effects and
corresponding gust response factors and background factors, and a wind tunnel model
of Tokyo Polytechnic University is also utilized. The gust factors and back ground
factors of responses of these two buildings under wind loading are calculated
respectively. The responses calculated by pressure time histories are compared to
those calculated by applying ASCE7-05. Methods to investigate universal equivalent
static wind load are applied to both buildings. Several equivalent static wind loading
(ESWL) methods are compared, and the universal ESWL method is applied to
WERFL building and another modified universal ESWL method is also utilized for
WERFL building.
