Consider the frame shown. Suppose that w = 16 kN/m. a) Determine (approximately) the moment the ground exerts on the frame at joint A. Hint 1 for Part A. How to approach the problem Analyze the frame using approximate methods for statically indeterminate structures with vertical loads. Apply the required assumptions regarding zero moment points in order to reduce the frame to the one that is statically determinate. Then, use the equations of equilibrium to determine the moment exerted on the frame at joint A. Hint 2 for Part A. What assumptions should be made to solve the problem Since the girder located within a building bent and subjected to a uniform vertical load is statically indeterminate to the third degree, an approximate analysis will therefore require three assumptions to make the girder statically determinate. Each girder having the length L may be modeled by a simply supported span of length 0.8L resting on two cantilevered ends, each having a length of 0.1L.…

Draw the shear-force and bending-moment diagram for the beam shown. Assume the upward reaction provided by the ground to be uniformly distributed. Let a = 3.3 ft, b = 3.2 ft, P = 20 kips, and w = 3.0 kips/ft. Label all significant points on each diagram. Determine the maximum value of (a) the internal shear force and (b) the internal bending moment. Note that answers may be positive or negative. Here, "maximum" refers to the largest magnitude value, but you should enter your shear force and bending moment with the correct sign, using the sign convention presented in Section 7.2 of the textbook. If the magnitudes of the largest positive and largest negative values are the same, enter a positive number. P A C D E Answer: (a) Vmax= (b) Mmax= a B b lb b lb-ft a
