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

Does this method only work with UDLs? What if there are vertical point loads on the girders as well?
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 ?

Ohhhh thanks It answered my question
