Abstract：A new kind of base vibration isolation masonry structure and an anti-seismic masonry structure were presented to improve the anti-seismic and damping performance of masonry buildings in rural areas. The two technologies have obtained the China national invention patent. Four rural housing structures were tested on shaking table. The test model includes: one base vibration isolation masonry structure model and its comparison model with anti-seismic technology measures, one special-shaped insulating concrete block with constructional columns masonry structure model and its comparison model made with normal concrete block and the corresponding constructional measures. Based on the experiment, the work performance of the base vibration isolation was studied; the anti-collapse capacity and wall failure process of the new anti-seismic structure were analyzed. The seismic design recommendations based on the above analysis were put forward. Experiments show that: the proposed base isolation system has the advantages of simple construction, low cost and good working reliability; When the peak acceleration reaches 0.1g, the base isolation system will start working effectively, which can significantly reduce the seismic effect applied to the upper structure; The proposed new anti-seismic system is more reasonable in anti-seismic design and has higher anti-seismic capacity, slower stiffness degradation, better ductility. And it can significantly improve the comprehensive seismic performance of rural housings. The new base isolation system and the new anti-seismic system proposed in this paper are suitable for applying in rural areas in China.
