Fig. 2 Statically indeterminate structure with 3 supports#

Exercise (Influence line support reaction at A)

Draw the influence line for the support reaction at A, assuming a positive support reaction to point upwards. Only indicate the values for which no calculations are required.

Exercise (Influence line shear force just left of B)

Draw the influence line for the shear force just left of B. Only indicate the values for which no calculations are required.

Exercise (Influence line moment in B)

Draw the influence line for the moment in B. Only indicate the values for which no calculations are required.

Exercise (Influence line shear force in D)

Draw the influence line for the shear force in D. Only indicate the values for which no calculations are required.

Exercise (Influence line moment in D)

Draw the influence line for the moment in D. Only indicate the values for which no calculations are required.

Exercise (Influence line shear force just right of B)

Draw the influence line for the shear force just right of B. Only indicate the values for which no calculations are required.

Given is the following structure:

Exercise (Influence line displacement of D)

Draw the influence line for the displacement of D. Only indicate the values for which no calculations are required.

Exercise (Influence line rotation of B)

Draw the influence line for the rotation of B. Only indicate the values for which no calculations are required.

Exercise (Influence line displacement of S2)

Draw the influence line for the displacement of S2. Only indicate the values for which no calculations are required.
