STUDI PERENCANAAN STRUKTUR ATAS JEMBATAN PELENGKUNG RANGKA BAJA TIPE THROUGH ARCH UNTUK PANJANG 120 METER PADA JEMBATAN CALLENDER HAMILTON TRISULA LAMA KABUPATEN BLITAR

The Trisula Lama Bridge is a connecting bridge that has access to Malang, Blitar, and Tulungagung areas across the Brantas River. The Trisula Lama Bridge is located in Boro, Kademangan Village, Sanankulon District, Blitar Regency. This bridge has a significant function for the economy because it is used for access to the distribution of goods and people for activities so as not to experience difficulties in traffic. The upper structure planning of this trident bridge modifies the through arch type steel frame arch bridge because it can also get the aesthetic aspects of the Blitar Regency area. The planning of the Trisula Lama Bridge was redesigned with a length of 120 meters, a width of 15 meters, and an arch height of 20 meters. In bridge planning using a combination of loading according to SNI 1725-2016 regulations. The analysis process in planning uses the STAAD Pro V22 Connect Edition program. Several types of profiles and qualities used in the construction of the Old Trident Bridge planning structure include Box 1100.800.30.30 (BJ55) profile edge girder, Box 1000.800.30.30 (BJ55) profile arch frame and I 800.400.20 profile. 25 (BJ55), hanging rods with strand cables with a diameter of 105 mm, wind ties IWF profiles 400.200.8.13 (BJ37) and 300.150.6,5.9 (BJ37), transverse girder profile I 900.400.20.28 (BJ55), longitudinal girder IWF profile 500.200.10.16 (BJ37). The deflection that occurred on the Trisula Lama Bridge was 142,819 mm which already met the allowable deflection at the center of the span not greater than L/800 which is 150 mm.
