Cantilever Method

These results of approximate methods have been compared with the exact method of structural analysis and STAAD. Views Read Edit View history. To browse Academia. RE: analogy of a cantilever If this is a simple portal, and the columns are of the same stiffne.

They are real different. This metthod shows both the values from this cantilever method analysis compared with the previous portal method analysis example results in square brackets. Already a member. Namespaces Article Talk.

The cantilever method is very similar to the portal method. We still put hinges at the middles of the beams and columns.

The Cantilever method is an approximate method for calculating shear forces and moments developed in beams and columns of a frame or structure due to lateral loads. The applied lateral loads typically include wind loads and earthquake loads, which must be taken into consideration while designing buildings. The assumptions used in this method are that the points of contraflexure or points of inflection of the moment diagram in both the vertical and horizontal members are located at the midpoint of the member, and that the direct stresses in the columns are proportional to their distances from the centroidal axis of the frame. The method is quite versatile and can be used to analyse frames of any number of storeys or floors. The position of the centroidal axis the center of gravity line for the frame is determined by using the areas of the end columns and interior columns. The cantilever method is considered as one of the two primary approximate methods the other being the portal method for indeterminate structural analysis of frames for lateral loads.


Points of inflection occur at mid span of beams. These methods are metnod approximate methods and they have been used successfully for the analysis of the structures. Register now while it's still free. March 17.

This is surely more long than difficult today with structural analysis packages. Read more. Use it at your own risk. RE: analogy of a cantilever Yes its simple portal frame.

    The behavior of a structure subjected to horizontal forces depends on its height to width ratio. Unknown 23 May at To learn more, view our Privacy Policy. It is not rocket science but it is also not something that one can explain in a forum like this.👨‍👧
