Abstract
Bridge become one of the important facility for transportation, bridge can
connect area with difficult terrain such as valley, river, sea, and etc. We know that,
the quality of bridge would be decrease as caused by the age increased bridge it
self, load operational, and the environmental condition. Also, the bridge structure
should be considered, especially the load strength on the connection. Connection
is important because it delivered load from bar to another bar, and it enable the
bar movement caused by expansion of steel shrinkage. This research based on SNI
1729-2015. Bolt connection planning should be considered 4 condition; Bolt Shear
Strength, Slip critical Strength, Bearing Strength and block shear strength.
Moreover, longitudinal section bar must paid attention in compressive strength,
and tensile strength. Compressive strength affected by 2 conditions, which Flexural
buckling, and torque Buckling. Then, tensile strength affected by 2 conditions, when
tensile on gross area , and tensile on net area. The output of connection planning
and bar analysis as a result from Train Bridge Reinforcement Structure steel with
Warren type. It can be concluded that, bolt connection on slide of main frame, cross
girder, longitudinal girder, and breising is compatible with SNI 1729-2015, the Rn
point had reach the safe point beyond the Pu capacity maximum point from output
SAP 2000.
