Abstract : Simple one-dimensional predictions of the response of drag-sensitive, steel-framed structures have greatly overestimated the peak deflections using the measured dynamic pressures, and commonly accepted drag coefficients for the beam, column and truss components. Renewed interest in the behavior of these structures has initiated recent efforts to explain the reasons for the discrepancies between analysis and experiment. Complicating the analysis is that the structures are covered with siding and roofing of a frangible type. A three-dimensional structural dynamic code was used to predict the response of the framed structures to drag loading. The objective was to see whether discrepancies might be due to oversimplification of the structural model and applied load distribution. The results of a series of three-dimensional calculations and the comparison of response with test data are reported in the paper. (Author)
