【摘要】 在提出带暗柱异形柱基础上,进一步提出钢筋混凝土带交叉钢筋异形柱这一设计方法。通过3根T形截面短柱抗震性能的试验研究,分析比较了普通T形短柱、带暗柱T形短柱和带交叉钢筋T形短柱的屈服荷载、极限荷载、屈服位移、弹塑性位移、刚度、延性、滞回特性、耗能能力等性能。试验表明加配交叉钢筋可明显提高T形截面短柱的抗震性能。更多还原

【Abstract】 New seismic design method, the setting of crossed reinforcing bars in specially shaped column is suggested after the proposition of the specially shaped column with concealed column. Based on the tests of seismic behavior of 3 Tshaped column specimens, the seismic behavior of the general Tshaped column, Tshaped column with concealed column and Tshaped column with crossed reinforcing bars is compared. It is proved that the crossed reinforcing bars in the short Tshaped column is able to remarkably improve the seismic behavior.更多还原
