Kravchenko S. Deflected mode of steel constructions with solid and discrete elastic fillet welds

Subject of Research: welded structures (beams) with continuous and interrupted flange welded joints. Target of Research: Development of methodology of calculations of welded structures with interrupted flange welded joints with consideration of elastic compliance of welded joints in longitudinal and cross direction. Methods of Research: analytical, numerical, experimental. Theoretical and Practical Results: there has been developed the design apparatus for determining the deflection mode of 2- and 3-layer constituent rods with continuous and interrupted elastic welded joints; nature of distribution and determination of concentration areas for shearing and transverse forces in flange welded joints of steel welded structures has been researched; approach towards determination of rigidity factor values for welded joints in transverse direction has been suggested; impact of structural factors at rigidity of angle joints has been researched. Novelty: methodology for calculation of steel structures with interrupted flange joints has been designed, which confirmed the fact that rigidity and strength of welded beams with interrupted flange joints has practically no difference with the rigidity and strength of analogous welded beams with continuous joints. Degree of implementation: within the design of Coke Dry Quenching Plant of Coke Oven Battery No. 10-bis at JSC "Alchevskkoks". Area of Application: during new construction, re-building, during preparation of normative documents, during studies.
