Fatigue Response of Bridge Deck Link Slabs Designed with Ductile Engineered Cementitious Composite (ECC)
Link slabs designed for macroscopically crack free concrete bridge decks system were experimentally tested. The property requirements of the link slab material were considered. Special focus was placed on the fatigue and durability performance. Introduction of a ductile Engineered Cementitious Composite (ECC) material is proposed for its ability to control crack width and to exhibit high ductil...
متن کاملAdvances in Life-Cycle Cost Analysis and Design of Civil Infrastructure Systems
Concrete infrastructure systems require large capital investments and resource flows to construct and maintain. An integrated life cycle assessment and cost model was developed to evaluate infrastructure sustainability, and compare alternative materials and designs using environmental, economic and social indicators. The model is applied to two alternative concrete bridge deck designs: one a co...
متن کاملDesign and Field Demonstration of ECC Link Slabs for Jointless Bridge Decks
The poor durability of concrete bridges throughout the US is an increasingly large concern for highway transportation authorities. With decreasing budget allocations for infrastructure maintenance, rehabilitation, and replacement, the need for greater durability is apparent. A main source of this poor durability is leaking mechanical expansion joints between adjacent simple spans of multi-span ...
متن کاملDesign of Engineered Cementitious Composite Suitable for Wet - Mixture Shotcreting
An engineered cementitious composite (ECC) suitable for wet-mixture shotcreting (sprayable ECC) in the fresh state, while maintaining tensile strain-hardening behavior in the hardened state, has been developed by employing a parallel control of micro-mechanics-and rheology-based design. In the development concept of sprayable ECC, micromechanics is adopted to properly select the matrix, fiber, ...
متن کاملEffect of Link Slab on Seismic Response of Two Span Straight and Skew Bridges
Highway bridges are frequently constructed as simple span structures with steel or concrete girders and a cast-in-place concrete deck, spanning from one pier to another. At each end of the simple span deck, a joint is provided for deck movement due to temperature, shrinkage, and creep. Bridge deck joints are expensive and pose many problems with regard to bridge maintenance. Elimination of deck...
