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
