摘要:
A masonry composite structure with lightweight concrete filled steel tube core column and thermal-insulation sandwich is proposed in this paper. In order to research the seismic performance of the wall, the low-cycle loading experiments on three different composite walls combined with one kind of technology by sliding isolation with glass bead and graphite were designed. Specimen one was lightweight concrete filled steel tube core column-regeneration brick wall, specimen two was lightweight concrete filled steel tube core column-flyash blocks interlayer-regeneration brick wall, specimen three was lightweight concrete filled steel tube core column-flyash blocks interlayer-adobe wall with end region regeneration brick. The failure characteristics, bearing capacity, ductility and hysteretic behavior were analyzed. In addition, the formula on bearing capacity of the masonry wall with lightweight concrete filled steel tube core column and thermal insulation interline was obtained. Meanwhile, the calculated results coincide well with the experimental ones. The researches indicate that the masonry wall with lightweight concrete filled steel tube core column and thermal-insulation sandwich has good seismic performance and it can be applied to the seismic design of low-rise masonry structure.
