Structural Assessment Of Highway "N" Power Substation Under Earthquake Loads, Genda Chen, Dongming Yan, Zuocai Wang, Seth Justin, J. David Rogers, Kazi Rezaul Karim Sep 2018

Structural Assessment Of Highway "N" Power Substation Under Earthquake Loads, Genda Chen, Dongming Yan, Zuocai Wang, Seth Justin, J. David Rogers, Kazi Rezaul Karim

J. David Rogers

In this study, the Highway N Substation was analyzed with a finite element model (FEM) for its vulnerability. The 'rigid' bus and electric switch components were characterized with full scale shake table tests. Each component of the substation was carefully modeled with due considerations of mass density, stiffness and geometries. Based on the FEM, modal analysis was conducted to identify the natural frequencies of the structure along with their corresponding mass participation factors. In response spectrum and time history analyses, the dynamic responses of main components, such as 'rigid' buses and switches, were evaluated. The magnitude and location of the ...
