Seismic Performance of an Integrated Underground
This study is focused on an integrated underground-aboveground structure system (Fig. 1) contains three above ground high-rise buildings and a large underground struc-ture.
Overhead to Underground Conversion
To better understand the requirements to convert an overhead distribution line to underground, one needs to understand the construction of both. The overhead distribution line typically uses
