框架梁下部纵筋在中间支座的锚固长度为:
A: ≥laE
B: ≥0.5hc+5d
C: ≥laE且≥0.5hc+5d
D: ≥labE且≥0.5hc+5d
A: ≥laE
B: ≥0.5hc+5d
C: ≥laE且≥0.5hc+5d
D: ≥labE且≥0.5hc+5d
举一反三
- 抗震框梁下部钢筋伸入中间支座 A: >=laE B: >=labE且>=0.5hc+5d C: >=laE且>=0.5hc+5d D: >=labE且>=0.5hn+5d
- 下面有关楼层框架梁中间支座下部纵筋锚固计算的判断,正确的是() A: 能直锚固长度lae B: lae与0.5hc+5d取大值 C: 能直锚固长度lae不能直锚取0.5hc+5d D: ≥0.6lae且≥0.4hc+5d
- 楼层框架梁在端支座直锚长度满足() A: ≥laE B: ≥0.5hc+5d C: ≥laE且≥0.5hc+5d D: 伸至柱外侧纵筋内侧≥0.4labE
- 楼层框架梁下部纵筋在中间支座内长度取()。 A: lae B: 15d C: max(lae,150) D: max(lae,0.5hc+5d)
- 楼层框架梁KL端支座直锚长度应取max(laE,0.5hc+5d),其中hc指的是
