Tall Building Response Parameters: Sensitivity Study Based on Orthogonal Factorial Experiment Design Techniques

Author(s)

James J. Filliben, Emil Simiu

Abstract

This work has two objectives. The first objective is to introduce structural engineers to the experiment design technique, whose future applications may include, among others: the total response of tall buildings, and the nonlinear response to failure of statically indeterminate structures, for which the duration of each run is large. The second objective is to show, by using the experiment design technique, that wind load factors depend significantly upon the uncertanties with respect to the natural frequencies of vibration and the damping ratios. Because this dependence is disregarded in the ASCE 7-05 Standard, wind load factors specified therein can lead to safety levels that are significantly lower for flexible buildings than for rigid buildings. Finally, the specification of wind speeds in terms of peak gusts introduces unnecessary errors and should therefore be replaced by specification in terms of sustained wind speeds.
