Daftar Isi:
- Jembatan Brunjung was built to replace jembatan yang previously been damaged. The condition of the bridge was previously very apprehensive brunjung 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. This bridge is located in the Village District Jalen Balong Ponorogo with a total span length of 40 meters. Upper structure (superstructure) of this bridge using segmental prestressed beam, while the sub-structure (bottom structure) using pile foundation. However, in this thesis, the author would like to plan the structure above it by using the composite beam as an alternative in the planning of the bridge structure and to the structure below continue using pile foundation. Planned composite beam using slab with 200 mm thick, and composed of steel profile which consists of 3 plates 300.12 mm for wing plate, 1 plate 1750.15 mm for the plate body, 4 plate to plate freshen 120.120.13 elbow. While girder diaphragm planned with WF profile 600 x 200. Dimensions abutmen planned with 5 m width, length 8 m, and height 9.5 m. As for the planned pier width 7 m, length 8 m and height 13.5 m. Safety factor for stability control and piers taken abutmen 1.5. To abutmen, in the absence of structural safety factor against bolsters = 2.708, a safety factor against sliding = 1.974, soil bearing capacity license (qijin) = 44.179 t/cm2 and maximum soil bearing capacity (qmaks) = 26.329 t/cm2. Abutmen on circumstances and the structure above, a safety factor to bolster = 8.212, a safety factor against sliding = 29.624, soil bearing capacity license (qijin) = 44.179 t/m2 and maximum soil bearing capacity (Qmax) = 233.152 t/m2. As for the pillars on the bridge axis direction, a safety factor to bolster = 54.518, a safety factor against sliding = 112.508, and carrying capacity of land a permit (qijin) = 233.146 t/m2. At the direction orthogonal to the axis of the pillar bridge, a safety factor to bolster = 18.754, a safety factor against sliding = 53.488, soil bearing capacity license (qijin) = 221.106 t/m2 and maximum soil bearing capacity (qmaks) = 256.036 t/m2. Pile on abutmen and pillars are planned using pre printed concrete piles (precast pile) with a diameter of 40 cm and a length of 20 m, with a total of 10 pole mast on abutmen and as many as 30 poles on the pillar.
