Use Moment Distribution Method to determine the shears and moments in the continuous bridge superstructure following all steps below. Clearly label each step and each value. The columns do not contribute to bending. Assume pinned connections at top of column. The beam is supported as follows: A - roller B - roller C - roller D - FIXED (F.FM) O 150 150 ft 150 R1 ENDONI B Ro ws Complete the following steps per steps outlined in course notes and in class example. 1. Calculate Member and Joint Stiffnesses 2. Draw 'exploded' structure diagrams with internal sign convention 3. Calculate Distribution Factors and Carry Over Factors 4. Calculate Fixed End Moments - using either procedure for pinned end condition 5. Setup Moment Distribution Table 6. Balance - Distribute - Carry over 7. Sum Columns - Iterate Step 6 as needed to balance joints 8. Organize Results - Calculate Reactions 9. Draw Shear and Bending Moment Diagrams (consider points of positive, negative, and O moment)
