Planning For The Construction of Cikeas River Bridge Wiht-Prestressed Beam Structure Method. of Housing Crv Residence Case Study

Along with the development of the times and technological advances, present a concept that is slightly different from the concept of ordinary reinforced concrete. The combination or active combination of high compressive strength concrete and steel with high tensile strength or prestressed cables produces a concept called Prestressed Concrete. Prestressed concrete is basically concrete in which the internal stresses of a suitable magnitude and distribution are given in such a way that the stresses caused by the external loads are resisted to a desired level. In reinforced concrete bars, prestress is generally provided by pulling the reinforcing steel. In this study, I as a researcher will plan the construction of the Cikeas River Bridge with the Strategic Prestressed Beam Structure Method. Case Study of CRV RESIDENCE Housing, located on Jalan Parpostel Raya, Jatiluhur Village, Jati Asih District, with a land area of 7.5 hectares. On the south side the housing is located in Jatiasih Village area with a land area of 2.3 hectares, and the remaining 5.2 hectares is located in Bojong Kulur Village, Bogor Regency. The two housing sites are separated by the Cikeas River flow. Based on the condition of the housing area which is divided into two, to connect the two areas a connecting bridge development plan is made. In the construction of this bridge it is planned to use strategic concrete which is installed on the bridge girder beam. Since this bridge has a long stretch with a width of 9 meters and a length of 23 meters, the bridge is planned with three supports each with a pedestal distance of 11.50 meters. The reasons and objectives of the writing of the final project Assess the load planning on the bridge structure, study the strategic beam profile planning, and study the planning of Tendon requirements and the location of the Tendon position on the strategic beam The method used in calculating the PCI Girder type prestressed concrete and the Post-tensioning system is based on the design and Calculation of prestressed girder beams (Precast) using the Post-tensioning method is obtained with a beam profile with a height of H = 90 cm and a width of 70 cm with a girder span of 11.50 meters consisting of 2 VSL Ø ½ inch tendons, Uncoated type 7 wire super strands ASTM A- 416 grade 270 with 27 strands and using main reinforcement Ø 13 mm, shear Ø 12 mm, and shear connector Ø 12 mm.
