The continuous frame ABC has a fixed
support at A, a roller support at C, and a rigid
corner connection at B (see figure). Members AB
and BC each have length L and f lexural rigidity
EI. A horizontal force P acts at mid-height of
member AB.
(a) Find all reactions of the frame.
(b) What is the largest bending moment Mmax in
the frame? Note: Disregard axial deformations
in member AB and consider only the effects of
bending.
