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

[@stevenbaugher8841]

I have steel fabrication company and we are transitioning into joist manufacturing. This video has definitely helped

Hi Drew, I have a question. Why doesnt the bottom chord of the joist connect to the column ? Thanks.

[@drewpotts781]

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

Cheak for radius of gyration for joist is important.and why can you explain sir

[@drewpotts781]

Radius of gyration effects compressive strength... and also stability during erection.
