Hi All,

Generally,plinth beams are provided to connect columns in both directions in order to reduce the length of the column and also to provide support to walls.

If we get the situation to provide beam to connect column in both direction and also we need to provide one more beam to support wall load which is too close to the beam which we have provided to connect column,
how to solve this efficiently??

Please refer the image for better understanding.

Thanks,
Ramu.

Hi, You can proceed not connecting plinth beam to column directly  ,Your column size will increase little bit more other than it should be fine, And model the same in your analysis tool.

Er.Ram,

In the first sketch u provided a plinth beam connecting the columns directly in Y direction which is more efficient way for structural stability. You can  use cantilever beam from column and then provide beam connecting the cantilever beam to carry the wall load.

If u do the other way as in the second sketch the connectivity to columns is only in x direction and not in y direction to the end columns.

Plinth beams are connected both in x and y direction in order to get a tie to all columns to act as a single structure which is good for reducing the uneven settlement as well a good system for seismic force.
You can refer the HB by Fintel for more details.

Hope my view will be one of the suggestions by others.
