Efficiency of Intensity Measures Considering Near- and Far-Fault Ground Motion Records

This paper focuses on the identification of high-efficiency intensity measures to predict seismic response buildings affected by near- and far-fault ground motion records. Near-fault has received special attention, as it tends increase expected damage civil structures compared that from ruptures originating further afield. In order verify this tendency, nonlinear dynamic 3D multi-degree-of-freedom models is estimated using a subset records whose distance epicenter lower than 10 km. addition, quantify how much demand may because proximity fault, another records, in range between 30 km, been analyzed. Then, spectral energy-based well those obtained specific computations record are calculated correlated several engineering parameters. From these analyses, fragility curves derived for both subsets It observed nearer fault produce functions with higher probabilities exceedance ones Results also show efficiency similar but varies depending parameter be predicted.
