Abstract
Kradenan bridge was built to replace the previous bridge was damaged. The condition of the bridge was previously very apprehensive Kradenan although this has been done during maintenance and repair, but the condition is always broken. This damage is generally caused by the condition of the bridge structure which could no longer bear the burden of the development of traffic passing through it. However, in this thesis, the author would like to plan the structure above it by using a hybrid composite steel beams as an alternative in the planning of the bridge structure. Hybrid steel plate girder girder whose profile is arranged or formed from the composition of different plate quality. In the hybrid composite steel plate girder generally wing composed of higher-strength steel from the body. More dominant bear the flexible wing body is more dominant bear shear. Burdens that must be taken into account in the planning of the bridge are as follows: primary load (dead load, live load, shock load.) Bridges the planning stages include: planning vehicle floor plate, cross-sectional design, planning wing plate, the stability control on the wing plate , the planning body plate, buckling stability control on the body due to the shear plate, the plate buckling stability control agency due to bending, shear connector design, joint design, planning girder stiffener support, planning support. Planned vehicle floor plate with plate thickness of 20 cm, pedestal principal reinforcement Ø16-50 mm, reinforced pitch Ø16-150 mm, reinforcement for (shrinkage) Ø9-100 mm. Beam master planned using WF steel profile 27x114 with a wingspan of 25.6 cm, 2.367 cm thick wing, height 64.56 cm, 1.448 cm thick body. Total voltage caused by the primary load: steel stress fibers upon =- 276.05 kg/cm2; stress fiber steel down = 2103.05 kg/cm2; fiber concrete stresses upon =-- 112.57 kg/cm2; stress fiber concrete bottom = -30.67 kg/cm2. Type stud = 22 mm-90 mm (qu = 138.6 KN), total stud (n) = 20 pieces, stud spacing = 52 cm. Connection plate body: connective plate thickness = 1 cm, thickness = 1.448 cm profile body, bolt diameter (d) = ¾ "(1.905 cm), number of bolts required = 12 units. Wing plate connection: connector plate thickness = 1 cm, thickness = 2.367 cm wing, bolt diameter (d) = ¾ "(1.905 cm), number of bolts required = 4 pieces. Welding 0.5 cm thick. stiffener beams WF 175x90 pedestal used with high-profile girder 17.5 cm, a wingspan of 9 cm, 0.8 cm thick wing, height 15.9 cm, 0.5 cm thick body, cross-sectional area 23.04 cm, weight of girder 18.1 kg/cm2. planning pedestal used "Elastomeric Bearings" T-EE1 (13 x 20 inches)
