In-structure shock of underground structures: A revisit with experimental investigation [PDF]
Engineering Structures, 2013 Abstract In-structure shock of underground structures subjected to ground shocks is investigated, both theoretically and experimentally. In the theoretical prediction, the ground shock is simplified to a triangular pulse with a rise time. It is found that the acceleration time history of the structure when the rise time of the ground shock is ...
