steel reinforcement different form main direction

[robyzou]

hi,

first think, sorry for my bad english.

I wan't to know how to calculate the section of steel reinforcement needed if the direction isn't the same of the main moment.

It's for a plate with a skew angle.

I just have to divide the section by the square of cosinus of the angle between the two directions ? or am i totaly wrong ?

Thanks for helping me.

well,

i've found information about Wood/armer method, is it the correct way to design this ?

I have never used it myself, but I understand wood armer is used primarily in the design of bridge decks to determine steel reinforcement requirements at different angles relative to applied moments.

thanks for your response.

It's exactly what i want to do, i have a 45° skewed brigde.

i've read this method is very (too) conservative ? isn't it ?

 

[Ussuri]

Pass. I am only aware of it and no nothing of its intricacies. You could try the Bridges Forum.

am i wrong if i said that the method Wood-Armer only concern assessement, and the concrete still design with the classic method ?
