Design a simply supported concrete beam bridge with a span of 20m, carrying a highway loading. The beam is reinforced with 12mm diameter high-yield reinforcement.
Cracking is allowed under SLS, but crack widths are restricted to specified limits (e.g., 0.1 mm).
Code of practice for design of concrete bridges (reinforcement, prestressing, durability). : Short-term elastic modulus depends on fcuf sub c u end-sub
BS 5400 covers the design of bridges, including substructures, superstructures, and foundations. The standard applies to bridges constructed from concrete, including reinforced and prestressed concrete. The code provides guidance on the design of bridges for various types of loading, including:
Designing a concrete bridge to BS 5400 requires a balanced application of limit state principles, precise traffic load modeling, and rigorous serviceability checks. By understanding the interaction between Part 2 (Loading) and Part 4 (Concrete Design), engineers can ensure both structural safety and long-term durability for major transport infrastructure.
Under Part 4, designers must choose the appropriate concrete medium: Reinforced Concrete (RC)
