Title of the articleExperimental studies of T-section steel-concrete beams
Abstract.The article is devoted to experimental investigations of steel-concrete structures. Steel-concrete structures are widely used in civilian buildings as floors and coatings. Overlap consists of a reinforced concrete slab supported by ribs. As the ribs are very often used steel beams of the I-beam. However, they have a low degree of fire resistance and corrosion resistance. Therefore, the steel girders of the I-beam on the side faces sometimes filled with concrete, which increases corrosion resistance and fire resistance of steel-concrete slabs. This article describes the design of models of steel-concrete beams. Before concreting, steel I-beam to the walls of welded stainless steel straps and beneath two rows skipped ?8mm valves on each side. Tests were carried out on the test press UMM200 to static loads. To determine the fiber strain on the beams, ribs and concrete slab on the surface glued electrical strain gauge. Deflections of beams determined by deflect meter of Burkovsky shift layers – using dial gauges. The test results obtained deformation deflections. Results obtained by treating the stress state of the normal section of the steel-concrete beam. The graphs shear layers, deflections. The analysis of beams in the elastic, elastic-plastic stage and the ultimate limit state was carried out.
Keywords.steel-concrete beams, T-section, experiments, strain, stress.
