只看楼主

一般梯板厚度按1/25~1/30取,但要计算挠度时,好多人(包括morgain) 只是取梯板厚进行计算,这样使挠度很难满足,加大板厚的同时,荷载也加大了。下面这篇论文说的就是这个问题。它建议的方法是:1.梯板的正截面与斜截面的计算,h0=t-as2.裂缝计算时,宜将算得的裂缝值乘以1.13.挠度计算时,h0=t+h1/5-as。h1为踏步的斜高这样计算是安全的,也证明了:梯板厚按正常的1/25~1/30是没问题的!

它建议的方法是:
1.梯板的正截面与斜截面的计算,h0=t-as
2.裂缝计算时,宜将算得的裂缝值乘以1.1
3.挠度计算时,h0=t+h1/5-as。h1为踏步的斜高
这样计算是安全的,也证明了:梯板厚按正常的1/25~1/30是没问题的!

当然,这只是一个试验得出的结果,这样的计算方法并未得到权威的认可。但可以肯定的是,这是安全的。如果审图公司不许这样做,那只能改了!:(

搞得这麻烦.计算挠度时按5/48直接打8折计算,也蛮好的.

规范也没有明确梯板的挠度限值啊,大家是怎么考虑这个问题的?

是否应考虑裂缝开展及长期作用影响,取B=0.85EI,E取短期弹性模量值一半?
