Viaduct bridge pillar and bridge girder design Eecel program and a project example

One of the most important factors that speed up transportation is the bridges. Due to the physical structure of Afghanistan, bridges are very important. As in the world, most of the new bridges in our country are made up of precast prestressed girder reinforced concrete bridges. There is no regulation on the design of bridges in our country. That's why the American State highways and transportation agencies used in Turkey (American Association of State Highway and Transportation Officials.-AASHTO) has been preferred design according to the regulations. In this study, precast prestressed reinforced concrete bridge with precast prestressed girder in Salihli district of Manisa city Bülent Ecevit junction İzmir - Ankara State Highway has been designed and analyzed by using CSI Bridge program by taking into consideration the AASHTO design conditions. In addition, the design of the prestressed prefabricated I-section bridge beam used in the bridge superstructure with varying openings has been developed by the Excel program. The bridge, which is considered in the research, has a width of 22.50m and has 4 lanes. It is designed for three openings of 30.35, 30.70 and 30.70 meters. In this study, firstly the studies done in this field are examined and general information is given about various bridges. The general layout and cross sections of the 22.50m wide 4-lane bridge considered in the study and the material properties used in the bridge elements are indicated in the third section. In the fourth chapter, the bridge design example hand solution, in the fifth chapter, the bridge 3D analysis, in the sixth section analysis/seismic design, in the last section, the results of the superstructure design and design, tables are given.
