Consider the structure and applied actions shown in the figure below.

The frame is subjected to a uniformly distributed load on $BC$ and a change in temperature in $AB.A$ is a fixed support and $C$ is a roller.

Analyse the structure using the qualitative analysis.

Qualitatively analyse the frame shown and determine:

the direction of reactions, axial force diagram, shear force diagram and bending moment diagram and the deformed shape by the distributed load on BC only;

the direction of reactions, the bending moment diagram and the deformed shape by the temperature change in $AB$ only.
