A Review of Recent Mathematical Models Made on Actual Buildings and the Accuracy of the Predicted Periods, Optimum Seismic Protection for New Building Construction in Eastern Metropolitan Areas

摘要

This report reviews recent analytical studies made on actual buildings for which both mathematical models have been developed and experimental measurements have been made to determine the fundamental periods of vibration. Three case studies are presented: a concrete shear wall building; a steel moment-resisting frame building; and a concrete moment-resisting frame building. These are followed by a brief review of analytical studies for which the measured period is obtained by ambient vibration tests, man-excited vibration tests, or forced vibration tests only. Each review gives a brief description of the building, the experimental tests performed, the mathematical model used, and a summary of results obtained. A review of studies is reported in which the periods computed by the mathematical model are compared to the periods actually experienced during earthquake excitation. Two tables summarize the results of the studies and list the percentage differences between the computed and observed periods for each building.
