Question

Difference between portal method and cantilever method

Answer 1

Answer:

The cantilever method is very similar to the portal method. We still put hinges at the middles of the beams and columns. The only difference is that for the cantilever method, instead of finding the shears in the columns first using an assumption, we will find the axial force in the columns using an assumption.

Answer 2

Difference between portal method and cantilever method:

• The methods portal and cantilever method are used For analysing approximate value of lateral loads be it due to wind or seismic variations.
• The difference in both the methods is where there used for example the portal method is used for buildings where the shear Mode is responsible for any kind of deformation in the building.
• While the cantilever method is used In case of buildings where the Mode responsible for deformation would be lecture mode .
