Abstract
The Shearing members of steel concrete and composite structure have been almost structure consist of latticed steel. However, recently according to development of welding process filled type steel members, welded members of plate, beam, column constructed with all welded structure, and H-shape steel, are going to be applied economically. The purposes of this study are to investigate phenomena of failure on shearing registance of filled type steel-concrete used H-shape steel, furthermore, relation of thickness of steel web, to first diagonal cracks, and ultimate shearing strength, and consider increasing of ultimate strength, and the tenacity to deformation until failure.
