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 ...

Analytical method for the mechanical response of buried pipeline under the action of strike-slip faulting

Underground Space, 2022
Buried pipelines are commonly damaged when laid across strike-slip faults, always leading to some level of destruction with fault movement. The moment of the neutral axis of a pipe section was obtained by integration, and the equations for the bending ...

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...
