Thickness of the webs varies from 450 mm (center of span) to 800 mm (above support). The cross-section height is variable, from 2.85 m to 6.50 m. Width of the top flange is 13.65 m and the bottom flange is 7.00 m. The cross-section is a single box girder. Longitudinal section of this span is presented in Fig.3. Cantilever consists of 11 segments with length from 4.4 m to 5.0 m.

Experimental results are compared to computational model realized in Midas Civil Software according to Eurocode 2.Ģ. Currently, monitoring is in progress on the highway bridge, which is at present still under construction. Monitoring of bridges shows real behavior of structure during construction and also in service life. The rheological effects like the shrinkage and creep have significant impact on stress redistribution and deformation of structures in the final construction stage in service life but also in various construction stages, respectively. proeng.2013.09.049Ĭonsequently, each individual segment has different age of concrete.

Monitoring and Numerical Analysis of Construction Stages on the Bridge Realized by the Free Cantilever MethodĪ Department of Bridges and Structures, Faculty of CivilEngineering, University of Zilina, Univerzitnä 8215/1, 01026 Zilina, Slovakia. The study results were compared to in-situ measurements that have been regularly carried out since the very early stages of construction.Ĭoncrete and Concrete Structures 2013 Conference The structural behavior assessment is based on numerical analysis and long-term monitoring of the prestressed concrete bridge. In ultimate cases, the excessive deformations may lead to serviceability problems, deterioration of aesthetics, and eventually early reconstruction of the bridge. Underestimating of above mentioned effects often causes that predicted deformations did not corresponded to real recorded values. In many cases bridge designer does not have enough information about all influences during the structure erection. The creep and shrinkage of concrete and temperature influence have been considered as main influences on deformation development with time.

Structure monitoring system during construction is very important for getting real information about deformation development with time and other influences that can affect the complex structural behavior.

Those structures have been very sensitive to prediction of deformation during their erection and service life, too. Abstract of research paper on Civil engineering, author of scientific article - Katarína Dolinajová, Martin Moravčíkįree cantilever method has become a very common method for the concrete bridges construction.
