Abstract

Transportation is an important part of human life and developing
mechanisms in line with the human civilization itself. One part is a transport
bridge. The bridge is an important element in the transportation system, serving as
a bridge serves traffic flow on it.
Seeing the importance of the function of a bridge then the bridge
construction must meet a wide range of existing standards. construction of
highway bridges with short spans, reinforced concrete construction should be used
as the main girder.
Long span reinforced concrete bridge being simulated is 15,4 m,
width 7 m carriageway, pavement width of 1 m and 1 m right side of the left side,
so that the total width of the bridge 9 m. Results of analysis of reinforced concrete
bridge calculation is derived calculations use the floor slab reinforcement D16 -
100 for flexural reinforcement and negative reinforcement D16 - 150 for flexural
positive. Backrest using reinforcement 2Ø12 pole. the girder plans drawn ultimate
moment (Mu) of 3286.78 kNm and shear girder ultimate plan is 728.18 kN.
Girder reinforcement is used by 14 D 32. To ensure that the girder is ductile, then
press the reinforcement is taken by 30% tensile reinforcement, so the use of
reinforcement 4 D 32. Reinforcement steel piles by 16 D 19 mm with spiral shear
reinforcement used cross section D Ø 12 mm
