A seismic strengthening method for Japanese wooden houses using corrugated thin steel plates is proposed. The steel plates are 0.5mm thick and screwed to the wooden frames. The plates cover the existing houses as exterior cladding and resist earthquakes. Behavior of the strengthened walls under lateral force is experimentally and analytically evaluated. The maximum lateral strength was observed as 16.6 kN/m under 5.5% lateral drift. Finite element analyses were conducted for the walls considering geometric and material nonlinearity of the steel plates and inelastic behavior of the screw connections. The behavior of the walls in the test was well simulated.
