Impacts of multiple bridge piers upon open channel flow based on LES
Shuili Shuiyun Gongcheng Xuebao, 2016 A large-eddy numerical model was used to simulate flow in a rectangular open channel blocked with a bridge pier or multiple bridge piers,focusing on effects of the bridge piers upon the flow characteristics and turbulent structures.

Bridge Failure Prevention: An Overview of Self-Protected Pier as Flow Altering Countermeasures for Scour Protection [PDF]
Civil Engineering Infrastructures Journal, 2021 The inherent scour process around the bridge piers needs to be considered and crucial to ensure a sustainable and economical bridge design. The performance of any scour protection/controlling devices around bridge piers is determined on how each device ...

A Superelastic Retrofitting Method for Mitigating the Effects of Seismic Excitations on Irregular Bridges [PDF]
Civil Engineering Infrastructures Journal, 2018 Irregularities in bridge pier stiffness concentrate the ductility demand on short piers; while not operating on the longer and more flexible ones. The existence of non-uniform, ductility demand distribution in bridges significantly influences seismic ...

Angewandte Chemie International Edition, EarlyView.The use of 1,1,3,3‐tetramethyldisiloxane (TMDSO) and potassium tert‐butoxide enables direct alkylation of weakly acidic carbon–hydrogen bonds with alkyl halides. Experimental and computational studies support the formation of a substrate‐associated hydride‐like base, providing a single‐step alternative to the classical deprotonation and electrophile ...
