I am working replacing an old silo is replaced with a higher one (68' old and 100' new) but same diameter. At door the old silo had #4 dowels @ 3" o/c. My question is if the old bar are cut (at top of foundation) and new dowel bars are to be placed (w/ Epoxy) in the foundation, the spacing...

Hello Everyone I am designing a pile cap (70' dia. and 2' deep) with timber pile type B (capacity 40 kips/pile) for a tank with total load of 10000 kips. I am using total of 261 piles as per arrangement. What should be the embedment depth (inches) of timber pile into pile cap. Thank you in...

Thank you all for your comments. As Mike suggested I used risa foundation and design my slab as foundation for a quick check

Hokie66: Ya you are right, the tank does not extend to the edge of the slab. So I got 1.4*(0.34*6*3 + 2.02*5*2.5 + .27*5 + 0.36*5)=48.3 And then should I multiply 1.31 to get an upper bound as msquared48 described? That will make it a total of 62.8 k-ft.

Can someone help me in calculating the negative moment (or moment at support) I am designing a pedestal with a circular slab of diameter 50 feet supported on a circular wall of 8" thick and 38 feet outer diameter. The thickness of the slab is 27" Loads: Self Wt of Slab = (150 lb/ft^3)*...

BAretired: Yes, I am providing two way bottom reinforcement (for positive moment), two way top reinforcement (minimum reinforcement). Radial reinforcement for negative moment and circumferential reinforcement (minimum reinforcement based on shrinkage and temperature) Please confirm my...

Loads on the Slab: Self Wt of Slab = (145 lb/ft^3)* thickness (2.33') = 0.34 kips/ft^2 Wt of Water = 438000 Gal = (438000*8.33)/(pi/4*48^2)=2.02 kips/ft^2 ------------- (8.33 is the conversion of Gal to lb and 48 is the diameter of the steel tank). This load as the area load over 48' diameter...

Thank you nutte

Hello I am designing a pedestal with a circular slab of diameter 50 feet supported on a circular wall of 8" thick and 38 feet outer diameter. The thickness of the slab is 28" (governed by shear design) I am looking for a good example for two-way reinforcement detail. Can someone give me any...

Thank you JAE and structSU10 But in my project there are only three of them, so my question again will be if we can calculate the length from flange tip to flange tip then can I use that as clear span or I still have to use from center line of web to web as clear span

When it says clear span on SDI (Steel Deck Institute), does it mean from center line (web to web) or flange tip to flange tip. Thanks in advance.
