Paper presents the generation and implementation of various types of earthquake sources in a 2D finite difference grid. The procedure used for computing dislocations on the fault plane is identical to both well known kinematic and dynamic models, since it was calculated by solving the equation of motion taking into account the stress drop and the shear strength of the fault. This scheme is supe...

A hybrid slip model combined an Asperity model and k model for predicting near-field strong ground motion is proposed in this paper. Firstly, the asperity model charactering lower wave number of slip distribution is estimated based on works of Wang (2004), Wang and Tao (2004a, b). Secondly, k square slip model charactering higher wave number of slip distribution was determined based on research...

In this article, topology optimization of two-dimensional (2D) building frames subjected to seismic loading is performed using the polygonal finite element method. Artificial ground motion accelerograms compatible with the design response spectrum of ASCE 7-16 are generated for the response history dynamic analysis needed in the optimization. The mean compliance of structure is minimized as a t...

Ground-motion simulations provide input time history data required for designing and assessing structures; however, the conducted by currently available tools only match design spectrum without verifying if statistical characteristics of duration are satisfied. A ground-motion simulation software was developed to resolve these issues. The employs machine learning methods amplitude, spectrum, fe...
