grade beam between footing
grade beam between footing
(OP)
i want to know what is the best position for the grade beam that connect the footings in the case of combined footing? is it from column to column or from the center to center of footings?

RE: grade beam between footing
but which clause in IBC speak about position of grade beam?
and what is the shear center of the footing?
RE: grade beam between footing
i mean the case to connect two combined footings or combined footing with isolated one
(i attach a sketch to the case i study)
my question is how can i connect these footings ?
is connecting the footing from two perpendicular directions only sufficient (as i hear)?
is it true to make inclined grade beam ? is it work well?

If the OP can't give us a PDF format version of his sketch, maybe you can, as you seem to know what he is talking about.

ibrahemnasr,
The sketch shows two single column footings with reasonably concentric loading, and two combined footings with two columns each. No grade beams are shown. What would be the purpose of grade beams?
RE: grade beam between footing
Why are the footings not centered under the columns? Should CF1 be rotated similar to CF16 in such a way that the c.g. of footing is in the same location as the c.g. of load?

RE: grade beam between footing
this sketch is apart of nearly large structure and this large footing dimesions due to large reactions from both gravity and earthquake loads so i want to connect them for some reasons the most important one is to prevent diffrential settlement
for this reason i attach this sketch for the footing to ask how can i put the grade beams especially between the combined footing and the isolated one?what is the best position for the grade beam?if i pit it between the centers of the loads it would be inclined is this true?is connecting the footing from two direction only sufficient or should i tie it from all directions?
thanks again

At the risk of repeating myself, why are the footings not centered under the column loads?
There is not have enough information to answer the question.

We definitely need more information, though.
