Title:A SDOF Model to Study Nonlinear Dynamic Response of Large- and Small-Scale R/C Test Structures

Abstract:The object of this study was to compare the results of earthquake-simulation tests of I small-scale reinforced concrete structural models with those of pseudo-dynamic tests of a I large-scale reinforced concrete structure. Comparisons were made by analyzing both sets of I test results with the help of a SDOF model. To develop the analytical model, the MDOF system was reduced to a SDOF system with the assumption that the displaced shape remains I essentially constant during the test. A hysteresis model based on the observation made in small- and large-scale tests of Ric structures was developed. Measured response histories of three small-scale and one large-scale R/C structures were compared with the calculated response histories of the SDOF models based on the properties of the tested structures. The sensitivity of the calculated response of the SDOF model due to plausible variations I in assumptions of input parameters were also investigated.
