Abstract: Three schemes of core column,constructional column and constructional column combined with core column are applied to a 12-storeyed concrete small-size hollow block building in seismic regions of intensity 8,and each structure is computed,According to comparing and analyzing corresponding 6~(th)～11~(th) floor masonry building,the applicable bound of different structural designs is discussed,and some advices on core column and constructional column designs of using concrete small-size hollow blocks in seismic regions of intensity 8 are pointed out.
