Fatigue Resistance of Concrete Bridges

This lecture covers the choice of inclination and verification of the resistance of compressed connecting rods in concrete bridges, focusing on the minimal inclination of the compression field. It discusses the impact of normal compressive and tensile forces on the core, plastic deformations, and the coefficient ko. The lecture also delves into the verification of the hypothesis for non-cracked sections, calculation of cracking moments, and stress analysis under various loads. Additionally, it explores the implications of fatigue on concrete and passive reinforcement, emphasizing the importance of fatigue checks and the calculation of admissible stress to prevent crack formation.
