摘要
提出了带暗柱的十字形柱；进行了4根剪跨比λ＝3．833的十字形柱的抗震性能试验．分析了轴压比对其抗震性能的影响；论述了暗柱的设置对提高十字形住抗震能力的作用．最后，将理论计算结果与实测结果进行了比较，二者符合得较好．
The crisscross-shaped columm with concealed colurnn is presented and the tests for seismjc behavior of 4 crisscross- shaped columns with shear span ratio 3.833 are completed. The influenne of axial pressure ratio on seisAnc behavior is analysed. The function of setting up concealed colurnn on raising seisdric capacity of crisscross-shaped colunm is discussed. And finally, theoretical calculating lesults are compared with real measuring ones, and both are conformable.
