Rigid Frame Analysis w/ Portal Frame Method
Posted 21 February 2012 - 06:30 PM
My question is when analyzing a rigid frame using the portal frame method (as shown in the SERM) the base reactions are different that if you looked at the frame as a whole and calculated the overturning moment and found the base reactions by a simple force couple. I know the base reactions are different when using the portal frame method because you assume a point of inflection at the midheight of the column and you calculate the foces about that point.
Am I wrong, or are these numbers supposed to be the same?
