To upgrade the level of rural housing to meet the increasing demand for comfort, safety, environmental protection and energy saving, a light frame structure system housing was proposed and designed. The light frame structure system takes a steel frame as the main structural body and ALC wall panel as the filling wall. A full-scale shaking table test has been carried out to verify its seismic performance and to study the seismic behavior and seismic response law of the light frame structure system under earthquake action on beam-column joints, wall-slab joints, and the building structure. The test results show that the wall panel has not fallen off, the joint connection is intact, and the structure has not collapsed. With the increase of input seismic intensity, both the acceleration amplification factor and relative displacement increase, while the natural frequency of the structure decreases gradually. Throughout the test, the main structural members remain elastic, and the inter-story displacement angle of the structure under a fortification earthquake of 6-degree is less than 1/250. Under the action of rare earthquakes of 7th intensity and 8th intensity, the inter-story displacement angle of the structure exceeds 1/250, but the structural deformation can be reduced by tensioning reinforcement support. The light frame structure system exhibited excellent seismic performance and can be used to improve the level of rural housing in the 6th intensity seismic fortification area. For seismic fortification areas above 6th intensity, the seismic performance can be enhanced by increasing the tension of tie bars.
