Abstract: Turkish bridge design standards were studied, with attention focused on the live load. The design specifications were compared with American design specifications. The major difference was that the live load in Turkish standards is given in tonnes; whereas, in American Association of State Highway and Transportation Officials-Standard Specifications for Highway Bridges (AASHTO 1996) it is in tons. Therefore, HS20 in Turkish standards is 10 percent heavier than HS20-44. Turkish bridges are currently designed to either HS20 or HS30, the latter being 65 percent heavier than HS20-44. There were some minor differences in other requirements, due to conversion from United States customary units to metric units. Three types of Turkish bridges were analyzed using a service load approach according to AASHTO (1996) using a Heavy Equipment Transporter as the live load. Service load approach was applied. Only the primary loads, dead load, live load, and impact were considered. The analysis did not include any modification for possible deterioration, damage, or aging of the bridges.
