4. The rigid frame below is the current design for a two-story commercial space.
a) Use the portal method and determine the approximate reactions (axial, shear, moment)
at the fixed column base at A.
b) In a revised design, the cross sectional areas of the columns have changed. The column
ADG has a cross sectional area of 10,000 mm?, the column BEH has a cross sectional
area of 20,000 mm?, and column CFI has a cross sectional area of 15,000 mm?. Use the
cantilever method and determine the approximate reactions (axial, shear, moment) at
the fixed column base at A.
