Desain Jembatan Menggunakan Beton Prategang Bentuk Box Girder Tipe Single Twin Cellular Berdasarkan Pembebanan Jembatan SNI 1726:2016 (Design Bridge Used Prestress Concrete Box Girder Type Single Twincellular Based on Loading of Bridge SNI 1726:2016)

Abstract

A bridge is a construction that is useful for launch at the same time. These obstacles are usually on other roads (air or traffic roads) Prestressed concrete bridges are the development of concrete materials. On prestressed concrete bridges provide a prestressing force that can compensate for the stresses that occur due to the load. Some forms of prestressed concrete bridges include girder boxes. Compared to other types, box girder types have several advantages, among others for bridges with a long span of 40 - 60 meters. In connection with that, over time, produces various types of loading experienced by the bridge structure. This is to find out the strength in supporting the loading on the latest conditions. In Indonesia, the new bridge loading regulation is the imposition of SNI 1726: 2016 bridge. In this final project, the design will be carried out on Grindulu Pacitan bridge which has a length of about 1000 m using a 60 meter span girder box so that the poles with SNI 1726: 2016 loading requirements Because the bridge width is 13.5 meters, it is necessary to add a wall to the girder sehinggan box which is a cellular single twin type girder box Bridge calculations are carried out using a simple span analysis with a span of 60 meters, and using SAP2000 V.11 application to calculate bridge slabs. Regulations used in planning are Standard Regulations for Bridge Load (SNI 1725: 2016), Concrete Structure Planning for Bridges (RSNIT-12-2004), Earthquake Planning Standards for Bridges (SNI 2833- 2008). Description of planning results using the AutoCAD program. The planning results of the bridge include a girder in the form of Box-Girder with a height of 3 m with a number of stands 810 with 18 tendons 0.4 m slab thickness with a main reinforcement D25-125. The lower structure includes the number of abutments 2 with a breast wall size of 1.3 x 14 m and a reinforcement ratio of 1%, the number of pillars of 12 pieces with a size of 3 x 2.25 m with a reinforcement ratio of 1.25%. and pile foundation on 10 pole abutments, while on 12 pillars.
