Strengthening of structures with UHPC – experiments and experience from application
Source abstract
Abstract
Abstract UHPC has been developed in the Czech republic for about 15 years. The paper shows some of the new footbridges with the deck made of UHPC and then focuses on repair and strengthening of existing structures. Extensive experimental work was carried out as a basis for applications. Different loading situations were examined so that the structural performance in serviceability and in ultimate limit states was investigated. Experience from the construction of structures made of UHPC, from extensive experimental campaign, and from literature resulted in development of the Technical conditions for production of UHPC, design and execution and for reconstruction of structures with UHPC, which were approved by the Ministry of Transport in 2024. The document provides a possibility to apply UHPC also in structures of the transport infrastructure. Finally, example of application of UHPC in repair of a heavily loaded road bridge is introduced. Now, the fourth stage of the repair is under construction. Experience from earlier stages led to minor modifications of the original technology.
