带暗柱Z形短柱抗震性能试验研究

Experiment and analysis of seismic behavior of short Z-shaped columns with concealed columns

提出了带暗的Z形短柱。通过3根Z形短柱抗震性能的试验研究,分析比较了Z形柱在两个工程轴受力方向的承载力、刚度、延性、滞回曲线和破坏特征,分析了暗柱对提高Z形短柱抗震能力的作用。试验表明加设暗柱后可明显提高Z形截面短柱的抗震性能。

The short Zshaped column with concealed columns is put forward in this paper. Through the tests of seismic behavior of 3 Zshaped column specimens, the bearing capacity, stiffness, ductility, hysteretic curves and failure characters in two engineering horizontal directions of Zshaped column are compared. It is proved that the concealed columns in the short Zshaped column can greatly improve its seismic behavior.
