Composite girders combine the structural efficiency of steel with the durability and stiffness of reinforced concrete, making them an ideal choice for bridges, flyovers, elevated corridors and long span infrastructure systems. At Purna, we provide Engineering services for composite girder structures from concept to construction.
Our capabilities include:
- Design and analysis of steel concrete composite girders, including plate girders, box girders and cellular systems
- Optimization of girder sections for load carrying efficiency, durability and economy
- Design of shear connectors, diaphragms, bracings and deck systems
- Preparation of fabrication drawings, shop drawings and erection plans
- Integration with precast and in-situ deck construction methods
- Checking for fatigue, vibration, serviceability and long term performance
- Detailing for constructability, ensuring ease of fabrication, transportation and onsite erection
- Coordination with geotechnical and substructure design for foundation and pier optimization.
