| Summary: | Bridge is a construction built to surpassing transportation or movement barriers
(traffic, river, gulf, strait). The wider of barriers that must be overcome is, the
longer dimension of the brigde that needed. A bridge that is planned to be built
should be able to bear the traffic loading safely and conveniently. The type of
bridge structure used in this Final Project is steel truss bridge with warren truss
configuration. This bridge will be used as railway bridge on Double Track of
Southern Railway Line. The bridgde will be built next to the existing bridge, with
same span, width, and height, that is 100 meter span, 5,4 meter width, and 15
meter (maximum) height.
The method of design are modeling the bridge structure using SAP2000 software
with BJ-55 quality of steel material, then bridge loading with Indonesian Railway
Technical Standard for Steel Bridge Structure 2006 as refferences. Next, do the
structure analysis with critical load combination, to get the demand force in each
structure element, so the structure element profile could be designed. As the
structure element profile designed, the structure deformation on serviceability
loading should be checked to allowable deformation referred to the standard.
Then, bolted connection designed using axial capaicty of the element connected as
demand force. And the last, abutment design using bridge bearings reaction
forces, and pile foundation design using soil condition and reaction forces on
abutment bottom. From this design, structure element profile dimension, bolt
number and gusset plate thickness requirements, dimension and reinforcement
required of abutment, and piles number, type, configuration, and pile driving
depth should be obtained. |
