Draw the influence lines for the vertical reactions at supports *A*, *B*, and *E* and the shear at internal hinge *D* of the frame shown in Fig. P8.19.

FIG. P8.19

To determine

Draw the influence lines for the vertical reactions at support *A*, *B,* and *E*.

Draw the influence line for the shear at internal hinge *D*.

**Calculation:**

Apply a 1 k unit moving load at a distance of *x* from left end *B*.

Sketch the free body diagram of frame as shown in Figure 1.

Refer Figure 1.

Consider the unit load at a variable position *x* to the left hinge *D*. (placed portion *BD* of the beam

Find the vertical support reaction *E* for portion *BD*.

Take Moment at hinge *D* from right end *E*.

Consider clockwise moment as negative and anticlockwise moment as positive.

Consider the unit load at a variable position *x* to the right hinge *D*. (Place portion *DE* of the beam

Find the vertical support reaction *E* for portion *DE*.

Take Moment at hinge *D* from right end *E*.

Consider clockwise moment as negative and anticlockwise moment as positive.

Thus, the equations of the influence line ordinate for
