PROBLEM TO BE SOLVED: To reinforce a frame-work itself without having to cover opening portions with additional walls while leaving existing wooden columns and beams intact, to freely remove an earthquake resisting wall, or to form a wide living space not intruded by the earthquake resisting wall in a simple way. SOLUTION: The rahmen frame for a reinforcement steel frame is fitted into the inside of a wooden frame-work per span unit independently from a wooden frame. Since the rigid frame structure having a characteristic of a wooden brace wall structure and a soft structure of a steel frame construction can have the same degree of rigidity in a horizontal rigidity, the rahmen frame structure for the steel frame can replace the wooden brace wall structure as a rational reinforcement method. The reinforcement with the rigid frame structure for a steel frame constituted only of columns and beams dispenses with walls with a new brace, which are necessary for a conventional method, enabling additional living space to be secured. Furthermore, modification work to the existing wall can be reduced to the minimum, reducing the execution period and construction cost. COPYRIGHT: (C)2005,JPO&NCIPI
