Abstract

Samota Bridge is a bridge crossing the Brang Biji River in Sumbawa Regency, West Nusa Tenggara. Samota Bridge will be redesigned using prestressed concrete with a type of PC I Girder with a span of 80 m and a width of 11 m. The bridge analysis standards used are loading standards for bridges (SNI 1725: 2016) and bridge planning standards against earthquake loads (SNI 2833: 2016). The loading analyzed is the analysis of own load, dead load, additional dead load, temperature influence, shrinkage and creep influence, brake force, earthquake load, wind load, prestress loss analysis, deflection and moment. Then, the reinforcement calculation is carried out on the PC I-Girder to the bridge elastomer planning. The results of the redesigned of the Samota Bridge with a span of 80 m (40+40) obtained the optimum height of the PC I-Girder needed is 2.10 m consisting of 4 tendons 2 on the left and 2 on the right with 12 strands in each tendon. The strands diameter is 15.24 mm and the duct diameter is 85 mm. The dead load (MS) received by PC- I Girder is 636,777.60 kg.m, the additional dead load (MA) received is 59,153.04 kg.m, 406,980 kg.m for "D" lane load, 8,183.25 kg.m for brake force, 3,003.25 kg.m for wind load and 179,378.73 kg.m for earthquake load. The total prestress loss due to anchor friction, friction in the cable, due to creep and shrinkage, relaxation and elastic shortening of concrete was 2,965.79 kN with a prestress loss percentage of 29.63%.

Abstract

Lombok Island is one of the earthquake-prone areas, located between two earthquake generators. Based on these conditions, it is expected that construction in earthquake-prone areas can meet the standards. Shear walls are one of the earthquake-resistant structural systems used to resist lateral forces. Three alternative shear wall shapes will be analyzed using the numerical method: the L, I, and T shapes. The types of loads to be analyzed are dead loads, live loads, and earthquakes. Drawing from the findings of the conducted analysis, it is discovered that the most effective shear wall position in resisting lateral forces is the shear wall located at the corner of the building, based on the values of the drift that occur in the x and y directions. In addition, increasing the number of shear walls can reduce the internal forces that structural components experience. The optimum drift value is obtained from alternative 1, the L-shaped shear wall (elbow), with a drift value of 0.000495 mm in the x direction and 0.000883 in the y direction.
