Want to see more videos like this? Let us know down below?

Hey there, thanks a lot for the compliment. We were thinking of a video on the portal method for analyzing lateral loads but its quite messy. Perhaps we can make it a very simple frame. Thanks for the request!

I apologize if I'm asking a stupid question. I'm just unfamiliar with this topic. But how do you find the vertical support reactions at the base of the column if we have a rectangular frame like this?
@jenikamcclay37014 жыл бұрын
Does this method only work with UDLs? What if there are vertical point loads on the girders as well?
@AFMathandEngineering4 жыл бұрын
If the point loads are spaced close enough and evenly you could probably assume it's a UDL otherwise no this doesn't work.

Hi sir, May I ask what is the difference between using approximate analysis vs. Fixed end moment formula for distributed load FEM= WL^2/12 ?
@AFMathandEngineering5 жыл бұрын
Not quite I understand the question, but approximate analysis were idealizing a concrete frame with fixity at supports somewhere between 50% fixed and 100 % fixed and assuming pins where the inflection point is typically located. Fixed end moments just assume fully fixed at the ends and calculate end moments.
