Study Notes
Moment Distribution Method
- A structural analysis technique used for analyzing continuous beams and frames
- It involves distributing moments at fixed supports and joints
- This method simplifies the calculation of forces and moments in indeterminate structures
Continuous Beams:
- Beams supported at multiple points along their length
- The moment distribution method helps determine the distribution of moments at the supports
- This method also allows for analyzing beams with sinking supports, meaning the supports may settle under load
Portal Frames:
- Structures that act as rigid frames and are commonly used in buildings
- The method is used to analyze portal frames without side sway (lateral movement)
- It helps determine the distribution of internal forces, including bending moments, shear forces, and axial forces
- The method is suitable for analyzing portal frames under various loading conditions
