The invention discloses a production method of steel having 225 MPa stage of low yield point and used for building earthquake resistance. The steel comprises the following chemical components in percentage by mass: C not more than 0.03%, Si not more than 0.1%, Mn not more than 1%, 0.02-0.06% of Al, P not more than 0.01%, S not more than 0.004%, N not more than 0.004%, 0.01-0.08% of Ti, Nb not more than 0.05%, and the balance of Fe and inevitable impurities. Through a serial of processes of refining, continuous rolling, heating, rough milling, electromagnetic inductive heating, fine milling, laminar cooling and winding, the yielding strength of the steel having 225 MPa stage of low yield point and used for building earthquake resistance reaches 200-240 MPa stage, and the elongation is greater than 50%; and the steel has excellent plastic deformation and impact toughness, and has the advantages of lower alloy cost, easy process realization, excellent weldability and excellent low-cycle fatigue performance.
