The design of bridge diaphragms is a challenging task for bridge engineers. Indirect bearing, significant tensile force at the top surface, revision and other openings require a massive and heavily reinforced structure.

In this webinar, you will learn how to model, correctly load and check a prestressed bridge diaphragm resulting in a full report with complete code-checks for ultimate limit state together with the serviceability limit state.

Commonly used methods, such as the Strut&Tie method, especially fail in checking the serviceability limit state-stress limitation, and crack width calculation. Cracks are a common phenomenon in diaphragms, which significantly affect the durability of the entire bridge. Crack width can be reduced, for example, by using transverse prestressing.

Are you sometimes struggling with how to solve any crossbar quickly, and safely, even with the use of prestressing?

With the innovative and more advanced Compatible Stress Field Method (CSFM) extended with prestressing, structural engineers can design and check prestressed concrete structures including discontinuity areas such as openings, partially loaded areas under bearings, or anchorage areas. All this packed in one application IDEA StatiCa Detail.
