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