at ~7:56 where you are showing the excerpt from AISC 360 Section F13, is the section modulus, S-sub-x, for Eq. F13-1 based on the gross cross section or the net cross section ?

Thanks alot. is the joist in the example is not laterally braced? (like bridging for top and bot. cords)

Hi Drew. Is there a way I could contact you? Am in need of your help on designing some floor Joists.

Cheak for radius of gyration for joist is important.and why can you explain sir
@drewpotts7812 жыл бұрын
Radius of gyration effects compressive strength... and also stability during erection.

Hi Drew, I have a question. Why doesnt the bottom chord of the joist connect to the column ? Thanks.
@drewpotts7813 жыл бұрын
Huimin Zhou, Joists are most often designed as simply supported. If the bottom chord is extended and connected to the column compression will develop in the bottom chord, voiding the simply supported assumption. Joists can be designed for end moments. The resulting joists is no longer a standard joist, but a specially designed joist. Thanks for the question. Drew

Hi sir, What if we make more holes on a secondary beam, wether it will affect the strength of the beam
@drewpotts7814 жыл бұрын
Yes it will. The more material you remove, the less strength the beam will have. Removing flange material will adversely effect the moment strength. Removing web material will adversely effect the shear strength.
@drewpotts7814 жыл бұрын
It all depends on the location of the holes and the stresses in the member... secondary or primary...
