Zapotochnyi R. Deformation and crack resistance of two-beamed rigid prefabricated monolithic bridge spans for complex constructions conditions

The thesis is devoted to studies of deformation and crack resistance proposed by the author constructive solutions of two-beamed rigid iron concrete prefabricated constructions of monolithic bridge spans for complex construction conditions. There are important experimental results of research designs with bridge spans based on the proposed design solutions, which is made in scale 1:10 with straight and curved parts of the different schemes and schemes of static load. The comparative calculation of experimental results of data on existing regulations is concluded. In the thesis there is demonstrated the quality indicators of the spatial distribution of deformation of idealized experimental designs according to different schemes for different static load circuits obtained theoretically using the FEM in the PC "LІRA-SAPR" in the task of setting linear dependency of materials. Here is also given the offers with calculations of two-beamed iron concrete constructions of prefabricated monolithic bridge spans on curved sections of transport facilities. Keywords: two-beam bridges span, difficult conditions of construction, research design, deformation, crack.
