Quantitative Resistance Assessment Of Sfrp-Strengthened Rc Bridge Columns Subjected To Blast Loads, Ahmad Alsendi, Christopher D. Eamon
Quantitative Resistance Assessment Of Sfrp-Strengthened Rc Bridge Columns Subjected To Blast Loads, Ahmad Alsendi, Christopher D. Eamon
Civil and Environmental Engineering Faculty Research Publications
The blast resistance of a typical reinforced concrete bridge pier column design was modeled with a nonlinear finite element approach that considers material damage, fracture, and separation. While varying concrete strength, amount of longitudinal reinforcing steel, and gravity load, the effect of applying an externally bonded steel fiber reinforced polymer (SFRP) wrapping was assessed. The presented approach uniquely quantifies column blast resistance in terms of charge weight. It was found that blast capacity was roughly linearly related to concrete strength and steel reinforcement ratio, the former of which is most influential. It was further found that a single layer of …
Use Of Uhpc Stay-In-Place Shells In Bridge Column Construction For Accelerated Bridge Construction, Nerma Caluk
Use Of Uhpc Stay-In-Place Shells In Bridge Column Construction For Accelerated Bridge Construction, Nerma Caluk
FIU Electronic Theses and Dissertations
This research utilizes Ultra-High Performance Concrete (UHPC), durable material that can be used to construct unique structural elements, to construct prefabricated shells that act as stay-in-place forms for circular bridge columns. These innovative structural elements are intended to (1) eliminate conventional formworks, (2) reduce the on-site construction time, (3) reduce life cycle costs by providing maintenance-free columns, and (4) improve the structural performance of bridge columns. The UHPC shell is placed around the column reinforcement that has been assembled using conventional methods, after which a UHPC step portion is cast at the column-to-footing interface to connect the UHPC shell with …

Bridge-management systems (BMSs) allow bridge owners to assess the condition of their bridge stock. However, not all BMS packages have the capability to formulate network-level bridge-rehabilitation investment strategies. This research has developed a decision-support system for bridge owners in the selection of the best strategy for bridge rehabilitation at the network level. The basis of the research is an available data set of 1367 bridge-inspection records for County Cork, Ireland, that has been prepared to the Eirspan BMS inspection standard. The developed system consists of a project-prioritisation procedure that builds on previous research, a methodology for the calculation of a …
