A web-based system for the selection of characteristic ground motions

A Machine-Learning-Based Software for the Simulation of Regional Characteristic Ground Motion

“…Therefore, a multicriteria objective function for ground motion is proposed. Seismic event parameters, target spectra (Sa, haz(T)), target intensity measures (IMs) for a specific site, structure of interest, and other conditions are investigated to simulate more reasonable ground motion [19][20][21][22][23][24][25][26][27][28][29][30][31]. The energy of seismic waves recorded at a station is related to the strong motion part of the recorded ground motion.…”

“…For a given acceleration a(t), velocity v(t), or displacement d(t), Ref. [29] defined the strong motion part of the recorded ground motion as the fast-growing region of the integral, where f(t) is any of a(t), v(t), or d(t). The time interval at which the maximum contribution of this integral occurs is defined as the strong motion duration.…”

“…Ref. [29] defined the 5-95% time interval as the ground-motion duration. Therefore, it is commonly used in seismic hazard analysis [18,19].…”

“…Thus far, researchers have developed ground-motion-selection software or frameworks based on different methods [27][28][29]; however, procedures for developing ground motion simulations using advanced methodologies are lacking. Although some methods have been proposed for synthesizing ground-motion records that meet some of the statistical characteristics, the current theoretical approach does not consider user-oriented applications [31].…”
