Summary: over the years the application of reinforced concrete bridge beams prestressed (BTCT DƯL) height low-beams a hollow, somewhat in response to the rhythm structures for the construction of bridges in the MEKONG DELTA. However, in the practices and the application of this product in many works of transportation shows need to have the perfect new research to improve economic indicators advanced, their techniques. This is the basis for the creation of the kind of money DƯL BTCT pressure construction beams available, cross-sectional shape T backwards. This is also the products in the subject DT103013.The last time shows a number of bridges have been built with application of the girder type. Assessing its efficiency in practice will help improve T-beam type product for upside in the future. That is the purpose of this report.
