Advanced Scalar-valued Intensity Measures for Residual Drift Prediction of SMRFs with Fluid Viscous Dampers
Abstract
Maximum Residual Inter-story Drift Ratio (RIDRmax) plays an important role to specify the state of a structure after severe earthquake and the possibility of repairing the structure. Therefore, it is necessary to predict the RIDRmax of Steel Moment-Resisting Frames (SMRFs) with high reliability by employing powerful Intensity Measures (IMs). This study investigates the efficiency and sufficiency of scalar-valued IMs for predicting RIDRmax of two sets of the 3-Story, 6-Story, and 9-Story SMRFs with and without using linear Fluid Viscous Dampers (FVDs). Incremental Dynamic Analysis (IDA) was performed with considering RIDRmax as engineering demand parameters using Opensees. Results of analysis showed that two scalar-valued IMs of IMM(α=0.5 ) and Saavg M-D had lower values of the variations of standard deviation of natural logarithm of IM of RIDRmax, σlnIMRD, which shows the efficiency of these IMs. Moreover, these scalar-valued IMs achieved higher p-values with respect to seismic ground motion features of M, R, and Vs30, which shows the sufficiency of assumed IMs. Therefore, two scalar-valued IMs of IMM(α=0.5) and Saavg M-D are proposed as optimal scalar-valued IMs for predicting the RIDRmax of SMRFs.
