RTA said the second phase work also includes the construction of second deck bridge
of two lanes in each direction to serve the traffic movement on Al Asayel Street and to upgrade the surface intersection to reduce the waiting time at the existing intersection from three to less than a minute.
This was proven by comparing the measured strains and deflections with those obtained from the CIP concrete deck bridge
. Therefore, the use of threaded rods as discrete shear connectors and HSS formed shear pockets at 4 ft.
FHWA's recently released Manual for Design, Construction, and Maintenance of Orthotropic Steel Deck Bridges
(FHWA-IF-12-027) presents a comprehensive guide to this technology for bridge design.
Another case study of a 97.5-m long open deck bridge
located in Western Canada consisted of one 46-m deck truss, and three deck plate girders measuring 21.8 m, 15 m and 11.7 m in length, two of which are suspended and connected to stringers projecting beyond the end floor beams at each end of the deck truss.
Bridge designer Parsons Transportation Group, Phoenix office (PTG) designed the new 1,604 ft long, 95 ft wide concrete deck bridge
, which extends 30 ft above the river bed.
Other works includeupgradingfrom a surface signalised junction to a flyover junction comprising of a deck bridge
of three lanes in each direction to better serve the traffic movement on Latifa bint Hamdan Street.
"The subsequent load testing confirmed the desirable performance of the UHPC waffle deck bridge
It was found that the load distribution factor equation from the standard specifications for highway bridges, 16th edition, American Association of State Highway and Transportation Officials extensively overestimates the load distribution factors of FRP deck bridge
Meanwhile, state highway officials and other public officials backing the state's preferred design are insisting the planned five-span deck bridge
will make a distinctive aesthetic statement of its own, and at a lower cost.
Seim agrees: "Designers will create a successful orthotropic deck bridge
if they use these codes," he says.
