HISTORY OF CONCRETE APPLICATION IN DEVELOPMENT OF CONCRETE AND HYBRID ARCH BRIDGES

Young engineers live in a permanent state of now and today without any connection to the past, which is missing even in their lifetime. This makes the historians and their task to remember what others have forgotten even more important. In this overview development of concrete as a material and contribution of the concrete application history in development of bridges, with the emphasis on arch bridges is shown. Some examples of concrete and steel combinations in order to employ the best properties of each material show the possibilities for new types of arch bridges. Biographies of famous engineers, designers and builders with their most important achievements are shortly presented. Accomplishments of Bridge Chair of the Zagreb Faculty of Civil Engineering in the development of concrete application and concrete bridge structures design procedures trough the educational, scientific and professional work are elaborated.
