Post-tensioned bridges are a type of bridge construction that utilizes high-strength steel tendons or cables within the concrete structure. These tendons are tensioned after the concrete has set, applying compressive forces to the concrete, which enhances its strength and durability. Post-tensioned bridges are often preferred for their ability to span longer distances and carry heavier loads compared to traditional bridges, making them suitable for various transportation infrastructure projects such as highways, railways, and pedestrian bridges. This thesis delves into a comprehensive investigation of the occurrence and behavior of cracks specifically in post-tensioned bridges, with a primary focus on the critical aspect of structures subjected to tensioning forces.
