Abstract
The paper presents only some problems of design and constraction of the bridge. The active provides the results of the research out composite muilti-span prestressed reinforced concrete beam for time building bridges. Comparison of experimental and theoretical sizes. Values of crack resisting, deformation property and strength index are received, work stages and studied slabe collapse odes are also described. The characteristic stage of the tensely deformed state are selected. State and practic making of multi-span iron concrete constractions by high productive modern technology. The analysis of the got results of experimental research is executed. The investigation of the large-scale bridge structure with bringing them to failure, thus avoiding the scale factor effect, is very important. Improving methods for calculation will provide the lower expence of materials when designing rainforced concred strutuctes and allow more efficient using all elements that make the constraction.
