Analisis dan Desain Jembatan Frame, Kolom “V”, Box Girder, dengan Mempertimbangkan Beban Gempa

Abstract

The growing of economic, social, cultural and environmental influenced by the availability of infrastructure, such as bridges. The bridges often used as a city icon. Selection of bridge structures important to adapt the structural strength and stability, serviceability structure, durability, ease of implementation, economic, and aesthetic. Strength of bridge structure in Indonesia is strongly influenced by earthquake load. Therefore, the construction of flyover Simpang Jam Batam needs to be built and studied. This study aims to analyze and design the frame bridge with "V"column and boxgirder, consider to earthquake load, and design reinforced concrete structures. The methods are data collection, preliminary dimension, modeling in CSI Bridge, and reinforcement design. The study started at April to July 2013 in Department of Civil and Environmental Engineering, Bogor Agricultural University. The result is the maximum forces obtained occurs in combination ULS-4a and SLS-4a, that moment values are 66298.6 kNm and 37494 kNm, whereas shear force values are 9735.71 kN and 6346.73 kN. Based on the results, boxgirder flexural reinforcement at top slab is D19-100 and D19-200, bottom slab and web are D16-150. Meanwhile, boxgirder shear reinforcement needs only at web is D16-150. Column "V" reinforcement is D25-150 to flexural and D16-150 to shear.
