I have designed a circular concrete base foundation and I have inserted a concrete pole mast. But the workers missed the job and the pole mast is not in the center of the base. How do you verify the minimum edge distance ? The base is 3 feet diam. and the pole mast is 10'' dia. The minimum edge...
Hi,
I have a project where I need to lower the basement floor. I want to do a "L" wall in front of the existing foundation wall. If the existing wall carries a linear load of "w" what will be the lateral pressure under that wall which will push on my new "L" bench footing ?
Thank you,

Hi,
I have to design a baseball backstop net structure. Total height is 60 feet. The first 16' feet is a chain fence 2x2 ga #6 (0.192'' dia.) and the rest will be a nylon net.
My client is asking for a free standing pole. I'm not sure how to determine the wind pressure on the net. Is it just...
Hi,
Anyone has a guideline or design example for a foundation for impact machine ? I have a die cast machine, the manufacturer is giving : Machine weight 155000 lb, the horizontal shake force at 140 RPM is 31500 lb and vertical shaking force is 15000 lb.
Thank you for helping

Hi,
How do you determine the pressure of the concrete fill in a circular concrete hollow foundation in which I have a concrete pole. I'm leaving 2 inch all around the pole to fill with concrete. But I want to know if the filling is done with 4000 psi concrete is it sufficiant? how can I...
Hi,
I have a rounded taper steel mast 40' long. It is made of a steel plate rolled and bended to form the pole. I was wondering if there is a way to calculate the force acting on the longitudinal weld ?
Anyone has an idea ?
Thx

Hi,
I have a wood stud and I'm fixing another wood element (cantilevar) (see image attached) how do you determine the how the column (stud) will bend and how to calcultate the flexure ?
Thank you for any help

Hi,
How do you verify the ground stability for an utility wood pole ? I know that the rule of thumb is 10% of the lenght plus 2 feet. But is there a way for more accurate design based on the type of soil and bearing resistance ?

Hi,
I have to verify a wood structure that was affected by fire. I was wondering if there was a normalized code verification. How do you evaluate the resistance of a wood section affected by fire. Do you just remove a the burned layer and re evaluate the good wood section ?
Any experience to...
Hi,
My geotechnical gave me a soil capacity (considering a 1 inch settlement). I was wondering when evaluate the reaction force on that footing. Do I have to add snow loading ? All my books are only mentioning the DEAD LOAD and the SERVICE LOAD (LIVE) but nothing about the SNOW load. My...
Hi,
I have a wood connection problem. If I have a [2x12] laying flat and I have a bolt with a washer. How do you calculate the bearing resistance of the wood under the washer. The force acting on the bolt is perpendicular to the wood. (see image below)
thank you
Hi,
I have a steel tank with diameter of 16' and height of 32'. The base is flat and anchored to the slab with 16 anchors (1.25" dia = 0.104 ft). The weight of the tank without any content is 5000 lb.
I'm not sure how to use the equation in API-650 (Section 3.11.3) Where the tension per anchor...
Hi,
See the PDF attached. I have a concrete basin with a particular shape. I want to avoid any concrete cracks etc. How do you determine where to place the joints and how many concrete pour section will be required ?
Anyone knows a guide for such construction ?

Hi,
In SAFE 12, if my column has a DROP panel and a CAPITAL, do I need to apply the option of including a rigid zone over my column ?
Also, if I do include it, anyone knows if that rigid zone is applied over the DROP and CAPITAL region, or it is only assigned to the column region ?
thank you,
Hi,
Is there a mathematical relation between the flow/current of a river and the pressure against a wall. I have to design a new foundation for a house that was dammaged last year by the flooding, flooding is happening each year in that region, but last year it was very bad. Last year the...
Hi,
In a plain concrete beam, what is the value of the effective depth ? Do we take the full depth of the beam or if the ACI code is limiting us ? I don't see the article. Thanks for helping
