Organic Prestressing Impact in Multi-Span Large Deck Construction

This paper shares research, experiences and landmar k projects where the organic prestressing technology (OPS) contribut es to establish new limits in well-known construction methods. The paper is focus ed on the critical range of spans¬ 70m to 100mc¬ for multi-span viaducts. After a brief state of the art, introduction to OPS and description of some practic l ases, solutions to overcome the previously mentioned technological cha lenges are presented.
