PURPOSE: A steel concrete structure system is provided, which is economical and effective by using a tension member to the whole cut end of structural steel, can be applied on apartment construction by reducing floor height sharply, can reduce the dismantling expenses of a form by combining the form work and the fireproof covering work, is easy to execute the reinforcement work if the extension work or additional live load is necessary and prevents the occurrence of cracks by arranging steels on the most outer block. CONSTITUTION: A steel concrete structure system arranges structural steel along the lower end of a beam instead of a main root of a reinforced concrete beam to endure tensile force. As steel materials, a channel (2) or two angles are used and a plate can be used if a span isn't long enough; if using a channel (2), a channel having the same width as the width of a beam is exposed and installed on the lowest end of a beam, so that a tension member is placed at the most outer block of a beam and a steel member is more advantageous than the existing a steel reinforced concrete reclaimed in the middle of concrete in a profile capacity; if using an angle, two angles are installed on the both bottom corners of a beam and a truss bar (4) or a plate piece is attached after welding to bind two angles; if using a column, each angle is arranged on four corners of a column to play as a column main reinforcing bar and a truss bar or a welding wire net is installed vertically between the inner face of an angle; if using a channel, two channels having the same width as the width of a column are installed and two truss bars or a plate piece is attached after welding to the inside of a flange.
