PURPOSE: A multiple step beam-column connection method for economical design of steel moment frame is provided to reduce floor height by reducing width, height and cross section of steel beam. CONSTITUTION: A multiple step beam-column connection method for economical design of steel moment frame comprises next steps. A steel beam(100) cut in fixed length is located between steel columns(10) using a crane. A flange plate(40) is settled on the flange of the steel column and the flange of the steel beam and tied up by temperately fastening using bolts and nuts. The concrete is poured and cured.
