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, gasma1975

Thank you all for the help, the spreadsheet was very useful !

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...

Thank you for the help. I also found on Google a great book with examples, "INDUSTRIAL MACHINES Handbook for Practising Engineers by KG Bhatia"

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 Regards gasma1975

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 gasma1975

Thank you, I will try it...

Hi, I have a hollow structure round section dia. 10''. I have to drill a hole 1'' on one side only, I need to know how it will affect the flexural resistance. How to calculate the section modulus ? Thank you for helping gasma1975

Hi, I need to fill a gap, I tought using several washers. But I was wondering if there is a code issue, a limit on how many can be stacked up ? gasma1975

Hi, I have a steel pole fixed at the base and free at top. I need to plot the PM interaction diagram along the lenght, how do you do that ? thank you gasma1975

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 gasma1975

Thank you for the help I saw in some documentation that is not allowed to put concrete around a wooden pole, is it true ? normally what is the detail construction when you embed a wooden pole in the soil ? I guess you put gravel at the bottom, what is around the pole ? just the soil or can I...

I have 2 wooden mast 90 feet apart and a cable. At mid span I have a small flasing light 50 lb. I will have some tension in the cable because the maximum sag is near 4 feet. I'm trying to avoid any guyed cables for the wooden mast. How can I evaluate how deep the embedment will be and the...

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 ? gasma1975

The floor is made of [2x12] @ 12" o/c, What happened is that the contractor has just replaced the elements which were heavily damaged and for the rest he sprayed an inflammable paint covering some burned elements very hard to identify. When a city inspector saw this he stopped the whole worked...

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...

Thank you frv, this is exactly what my Geotech told me. Thanks all for helping, gasma1975,

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...
