摘要
提出了在 L 形截面短柱的腹板中设置交叉钢筋以提高 L 形短柱的抗震性能的设计方法。通过3根 L 形截面短柱抗震性能试验研究,分析比较了普通 L 形短柱、带暗柱 L 形短柱和带交叉钢筋 L 形短柱的承载力、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 L 形短柱的抗震性能。
New seismic design method of special shaped column with the setting crossed reinforcing bars is suggested in order to improve its seismic behavior.Based on the tests of seismic behavior of 3 L-shaped column specimens, the seismic behavior of the general L-shaped column,L-shaped column with concealed column and L-shaped col- umn with crossed reinforcing bars is compared.It is proved that the crossed reinforcing bars in the short L-shaped column is able to improve its seismic behavior in a great deal.
