THIS QUESTION NEEDS TO BE SOLVED USING FORCE METHOD AND ONLY FORCE METHOD NO OTHER METHOD CAN BE USED TO SOLVE.

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 and $D$ are pin supports.

Use the dimensions and load values in the table below. Analyse the structure using the force method.

Use the force method to analyse the structure for the combined action of a distribued load and temperature change acting simultaneously. Take the redundant as the horizontal reaction at $D.$

Complete your calculations to determine what is required below.

Determine reactions at A and $D$;

Draw the axial force diagram, shear force diagram and bending moment diagram

for the distributed load and the temperature combined.
