Question:

A frame ABCD is constructed of steel wide-flange members (W 8 ( 21; E = 30 ( 106 psi) and subjected to triangularly distributed loads of maximum intensity q0 acting along the vertical members (see figure). The distance between supports is L = 20 ft and the height of the frame is h = 4 ft. The members are rigidly connected at B and C.
(a) Calculate the intensity of load q0 required to produce a maximum bending moment of 80 k-in. in the horizontal member of BC.
(b) If the load q0 is reduced to one-half of the value calculated in part (a), what is the maximum bending moment in member BC?
What is the ratio of this moment to the moment of 80 k-in. in part (a)?
