Effects of tie beam length, width and overlap
stress on settlement of foundations have been investigated. In this
investigation square concrete footings have been used with dimensions (B × B × d) where (d) is footing depth and (B) is
footing width (1, 1.5,2 m).
Width of tie beam (b) has been taken equal to 0.25, 0.30, 0.40, 0.50 and 0.75
(m). Tie beam length (L) has been taken varying from B till 3B with same footing depth = 0.50
m. Effect of overlap stress on settlement as well as effect of tie beam width
and length on settlement has been determined. Also, the efficiency of tie beam
length and width has been obtained. An equation is presented to compute the
overlap stress zone in case of existing tie beam. It is found that the settlement increases with increasing the length of tie beam which
is clear after the effect of the overlap stresses zone. The width of overlap stress zone case of
existing tie beam has been found to be equal to (1.6 -1.75) B. The settlement of footings decreases with
increasing tie beam width. It is found that the settlement after the effect of
the overlap stress zone increases with increasing the length of tie beam.
