Abstract

Bridge are structures that are made to cross ravines or obstacles, such as rivers, railroad tracks, or highways. Gutter bridges are included in the type of water crossing bridge or also known as aqaduct. In actual conditions this gutter bridge has a lot of damage caused by several factors. Based on this, research is needed to re-plan the entire construction of the gutter bridge. The data needed is data from measurements on existing conditions and Malang city HSPK in 2019. Planning is done using modeling using STAAD Pro V8i software. The loading analysis method uses SNI 1725-2016 and for stem and connection control uses RSNI T-03-2005. The profiles used in this plan are the single profile of Isolation Elbow 65.65.9 in the upper main girder, the single profile of Isolation Elbow 60.60.6 in the transverse girder and upper bracing, and the single profile of Elbow Feet 55.55.6 on other trunks with type of steel BJ 37. From the analysis results obtained and the conclusion that the self weight of the entire upper structure weighs 814,068 kg, the largest compressive force with a value of 11,517,418 kg or 112,985,871 N, the bending moment in the diaphragm girder that supports the live load and dead load additional rod 109 is 838,874 N-m or 838,874.00 N-mm, the largest tensile strength is 4,187,521 kg or 41,079.58 N, the connection uses high quality bolt joints A325 type with a diameter of 16 mm and uses a gusset plate with a thickness of 10 mm, and the calculation of the required Budget Plan is Rp 159.067.800,00.
