樓梯計算問題

看過帖子說不好算，我不明白。請教。不就是高度除以級數嗎？
還有，如何把樓梯板去掉重做？地下室的樓梯一側是靠著地基外牆的不知道如何固定的。

rugao123: True, that for straight staircase

You have to know local code, most of times it is 7.5, but can be as high as 8.25. Ideal is 7-7.25 with 10" treads. Most comfortable to walk and easy for kids and old people is 7" riser with 10" treads. L shaped is slightly difficult, I just learned myself and redid my staircase, changed from 8.25 to 7.50. You also have to figured the headroom, code is 6.8, but the higher the better. Don't forgot to add 3/4 for the hardwood floor. Good luck.
