Be honest... do you fully understand internal stresses in a structural member? Cause I didn't. But once I did it changed everything. I broke out the Civil Engineering Reference Manual (CERM) for all you hardcore teammates out there.
Take some time and wrap your head around this PE exam review problem and get more confident in passing the civil PE exam. Column design may be scary at first, but its less about column design and more a discussion on internal stress calculations in a structural member. We break down a simple yet complex eccentrically loaded column design example together in order to pass the civil PE exam.
Reminder the civil professional engineering exam in spring 2021 is only a few months away! Tackle this problem and your one step closer to passing the pe exam and obtaining your professional engineering license.
The Civil PE exam will be here before you know it!

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

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!

I am the somebody, really helpful. I never really understood the eccentrical load problems.

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?

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

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.

Could you possibly point out where we could find this equation in the codes since the reference manual does not have it (CBT)

the sign would matter? is there a sign convention for the moment in this case?

Hi, thanks for the video. Since the question asks for max "axial" compressive stress, would that mean calculating only Force / Area?

@Kestava_Engineering 3 жыл бұрын

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.
