According to the textbook, fabrication errors cause stresses in indeterminate structures.

Using the slope-deflection equations below, determine the beam slope at C. Let P1 = 15 kips, P2 = 13 kips, L1 = 18 ft, L2 = 10 ft, and L3 = 14 ft. Assume EI = constant.MAC = EIθC / 14 + 34.44MCA = EIθC / 7 + –61.99MCE = EIθC / 7 + 45.5MEC = EIθC / 14 + –45.5

Draw the influence line for the moment at B. What is the line’s minimum value? Let L1 = 3 m and L2 = 11 m.

Using the method of consistent deformations, determine the magnitude of the reaction at B. Let w = 21 kN/m and L = 8 m.

Determine the fixed end moment FEMBA with a settlement of 1.1 in. at support B.   As in Chapter 16, include the effect of settlement in the FEM calculation.  Let w = 3.0 kip/ft, L = 20 ft, E = 29,000 ksi and I = 1,550 in.4.

The beam supports a single live load of 2,670 lb. Determine the maximum positive 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.

Determine the beam deflection at point H. Assume that EI = 2.74 × 1010 kN-mm2 is constant.

Assuming that the live loads are transmitted to the bottom chords of the truss, draw the influence line for the force in member BF. What is the line’s maximum value? Let L = 18 ft.

Using the method of consistent deformations, determine the magnitude of the reaction at A. Let w = 19 kN/m and L = 7 m.

Draw the influence line for the shear at B. What is the line’s maximum negative value? Let L1 = 3 m and L2 = 13 m.
