Abstract

The research and comparison of traditional and composite method of reinforced concrete slab reinforcement is carried out in the article. The administrative office building was considered. By means of the software forces in an overlapping plate were defined. Taking into account the complexity of the pre-tension of composite elements, the calculation was made taking into account the initial stress-strain state in the cross section. All calculations of the stress-strain state of the section are performed using a nonlinear deformation model. Graphic images of the results calculation are shown. Show the diagrams of strains and stresses in the cross selection of the element under the action of the initial and calculated moment, as well as the characteristic parameters of the stress-strain state. MBRACE LAMINATE lamellas produced by BASF were used as reinforcement materials. The influence of the reinforcement method using a composite material on the load-bearing capacity of the slab is assessed. The estimation of economic efficiency of the use of two methods of reinforcement is made.
