초록

Nonlinear static and dynamic analyses are commonly used in seismic performance evaluation. To achieve the accurate results of nonlinear analyses, modeling parameters should be determined accurately for structural members. In this study, the values of modeling parameters provided in ASCE 41-17 for diagonally reinforced coupling beams (DRCBs) were evaluated whether those values accurately reflect the measured behavior of DRCBs. To imporve the accuracy, this study proposed empirical equations to determine the values of modeling parameters for DRCBs. For this purpose, the test results of 52 DRCB specimens were collected, from which the parameter values of c, d, e Qmax, Ie/Ig were estimated for individual specimens. The empirical equations of these parameters were developed based on the measured values. The accuracy was verified by comparing the calculated and measured values of modeling parameters.
