Please solve a problem involving steel hollow section with diametrically opposite eccentric load. The column is fixed in ground and free in air on other end. Also there is lateral load on the midsection of the column. Appreciate your guidance.
Nice video! On geotech we have this equation for eccentric loaded footings: Qmax=Load/BL x (1+(6e)/B) Qmax=110/1024 x (1+6x5/32)=0.208 kips/in2 where e = eccentricity = 5 in B=width and L= length (in this case both 32 in)
yes Luis - great equations, structural engineers use the same ones for footing bearing pressure checks, based on the allowable soil parameters given by the geotechnical engineer!
Just a thought, since the NCEES came out with a reference handbook (Beta), for future videos, you should try to reference that since it’ll be going to CBT after October?
I had no idea Jeff! I'm looking it up now and will check it out. I think that's a great idea to get that integrated into our design practice. could be VERY helpful
Great video! Thank you. In the new online exam, the Civil Handbook we are given seems to contain far less info than the physical book. For example, I could not find the equation you used to find stress. How would you recommend dealing with this?
Hi Ivie, unfortunately no, the internal bending stresses due to the eccentric load still breaks down to additional axial loading along the extreme fiber of the column. so it would be the combined axial + bending stresses.
S = I/c, not c/I
Love your explanation!
Glad it was helpful!
Amazing explanation ! Finally a clear and concise explanation on the plus/munis sign. Thanks man !

this was a great video. That kind of moment addition and subtraction applies to interaction diagrams too
This clicked for me! Eccentric loads explained very thoroughly...thank you!!
Glad it was helpful!
I am the somebody, really helpful. I never really understood the eccentrical load problems.

Could you possibly point out where we could find this equation in the codes since the reference manual does not have it (CBT)
Just wanted to say, this is a great video. Amazing explaination of everything involved.
Much appreciated!

Is it allowed to open the AISC book during the exam?
youll be given an electronic AISC I believe!
Hi, thanks for the video. Since the question asks for max "axial" compressive stress, would that mean calculating only Force / Area?
Hi Ivie, unfortunately no, the internal bending stresses due to the eccentric load still breaks down to additional axial loading along the extreme fiber of the column. so it would be the combined axial + bending stresses.
the sign would matter?
is there a sign convention for the moment in this case?
I want to fully understand stress
