Abstract Ground shaking, whether it is due to natural or induced earthquakes, has always been a matter of concern since correlates with structural/non-structural damage and can culminate in human anxiety. Industrial activities such as water injection, gas sequestration waste fluid disposals, promote seismicity consequent ground shaking that hinder ongoing activities. Therefore, keeping mind the...

In violent earthquakes, ground motion is considered to change dramatically in the process of spatial propagation. Strong spatially varying exists near fault area, and it can cause large-span large stiffness structure be damaged. this paper, a typical long-span steel box arch bridge selected as an engineering case. order simulate variation accurately, records that sampled former earthquake are u...

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...
