Am I understand the m correctly? My understanding is that when calculate a single span potal frame,m always equals 1,because there alway be a column which Ned is less than the average.And for double span frame,which the inside column NEd is usually much larger than the other two,so m equals 1 most times.
I m confused because I saw a software tutorial vedio,in which the presenter input m=2 for a single span portal frame

m is the number of columns in a row including only those columns which carry a vertical load NEd not less than 50% of the average value of the column in the vertical plane considered
