A great majority of structures being built today are statically determinate.

The beam supports a single live load of 1,500 lb, a uniform live load of 550 lb/ft, a uniform dead load of 100 lb/ft. Determine the maximum positive moment that can be developed at point B. Assume the support at A is a pin and C is a roller. The influence lines for VB and MB are shown, along with the peak values of the influence lines.

Using the method of consistent deformations, determine the magnitude of the reaction at C. Let w = 27 kN/m and L = 8 m.

Assuming that the live loads are transmitted to the bottom chords of the truss, draw the influence line for the force in member BC. What is the line’s minimum value? Let L = 16 ft.

Draw the influence line for the shear at B. What is the line’s maximum negative value? Let L1 = 5 m and L2 = 8 m.

Assuming that the live loads are transmitted to the bottom chords of the truss, draw the influence line for the force in member CD. The line’s maximum value occurs _______. Let L = 16 ft.

The beam supports a uniform live load of 554 lb/ft. Determine the maximum negative shear that can be developed at point B. Assume the support at A is a pin and C is a roller. The influence lines for VB and MB are shown, along with the peak values of the influence lines.

Draw the influence line for the shear at B. What is the line’s maximum positive value? Let L1 = 5 m and L2 = 13 m.

The truss is pin supported at A and rocker supported at E. Assume all members are pin connected. Determine the magnitude of the force in member AB. Let F1 = 450 lb, F2 = 850 lb, and L = 5 ft.

Assuming that the live loads are transmitted to the bottom chords of the truss, draw the influence line for the force in member CD. What is the line’s maximum value? Let L = 14 ft.
