Abstract:
Adobe structure of rural building is still used in many areas. In order to improve its seismic performance, a kind of masonry structure composed of regeneration brick and adobe, as well as glass beads - graphite foundation seismic isolation was proposed to reduce the seismic response. This full scale composite masonry building adopting the glass beads - graphite base isolation system was tested on a shake table. Based on the test, the structural dynamic behavior and damage evolvement process were studied. Main factors influencing the structural seismic response were analyzed, and the function of the isolation system to reduce the structural seismic response was clarified. The test shows that, the proposed masonry structure, composed of regeneration brick and adobe, with base isolation system, has good performance; under small earthquakes, the glass beads - graphite base isolation system is not activated, and the structural seismic response similar to seismic resistant structures; under moderate earthquakes, the base isolation system starts, and the seismic effect exerted to the upper structure is reduced; under major earthquakes, the base isolation system works well, which effectively mitigates the damage of the upper structure. The masonry structures composed of regeneration brick and adobe are suitable to apply in rural areas.
