Finite Element Analysis of Tie Beams under the Effect of Differential Settlement of Isolated Footings

The main objective of this paper is numerical analysis of the tie beams of isolated footings under the effect of differentialsettlement. 3-D simulation of the tie beams connected to isolated footings system by the finite element method wasconducted. The numerical results were compared with the results of mathematical simulation of the tie beams given byprevious research to determine the coefficient of semi rigid connection. The numerical result illustrate that the bendingmoments carried by the tie beam increase as the isolated footing width increased. Charts presented in the current papershow the effect of each parameter in the straining actions of tie beams that can be simply used by design engineers.
