Hi guys, I'm currently helping a client to deepen his pool. The shell of the pool is about 6-8in shotcrete. If we cut the bottom out and dig deeper, then add a new bottom, how would you make the joint between the new and existing shotcrete? Any experience to share will be appreciated.
When calculate masonry combined compression and flexure,
fm = P/At + M/St
One needs to calculate the transformed moment of inertia to get St.
What is the formula for It?
Hi there,
Did ya'll noticed that the moments given by the black book's beam charts are generally larger than that by the green book's?
For instance on the black book, for W14X43 with 20ft unbraced length, the available moment is 109.5 kip-ft;
On the green book, the available moment is...
Hi there,
First time to post here.
In ACI 530-05, teh allowable shear Eq.(2-5) says:
Bv = 350*(f'm*Ab)^(1/4)
I think the Ab should be Ap which is the projectd area for masonry rather than bolt area.
It does not make sense to use f'm to multiply Ab.
What do ya'll think?
