Development of an Empirical Relationship for the Prediction of Damping in Steel-Framed Buildings.
Abstract
Test data from the forced vibration and ambient experiments on actual structures are used as input to a regression analysis routine to develop equations for the prediction of damping in steel-framed buildings. The data is categorized by building height and building width (the dimension in the direction parallel to the applied forces). The best resulting equation is used as the basis for a new design methodology to predict damping. This methodology consists of using the prediction equation in a situation where a set of conditions are satisfied. These conditions pertain to the particular characteristics of the structure and the approximate level of excitation which is expected. It is anticipated that this methodology will be especially useful in the early stages of design. Included also are two type of sensitivity analysis which indicate the amount of variation in displacement response that can be expected by using the developed prediction equation. The results of both of these analyses indicate that the use of the developed equations results in good, usable predictions of damping values. Both the Engligh and Metric systems of measurement are used to develop the regression equations. (Author)
