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 performances of masonry buildings in rural areas. The two technologies have obtained the China national invention patents. Four rural housing structures were tested on a shaking table. The test models include: the base vibration isolation masonry structure model and its comparison model with anti-seismic measures, the masonry structure model made up of special-shaped insulating concrete blocks with constructional columns and its comparison model made up of normal concrete blocks and corresponding constructional measures. Based on the experiments, the working 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 and better ductility. It can significantly improve the comprehensive seismic performance of rural housings. The new base isolation system and the new anti-seismic system proposed are suitable for applying in rural areas in China.
