The test results show that the extreme negative pressures are the controlled pressures for the curtain wall design; the suggested values in the Code are unsafe at the center of the building while con- servative at the corner of the building. The equivalent static wind loads of the base moment are controlled by the mean wind loads. The wind induced accelerations present obvious across wind effects. The results obtained from this paper could be referred to similar projects.
