A foundation system with a RC slab has been modelled using a series of winkler springs. If the load is applied at the edge as shown below what will be the reponse of spring S15? Will it be in tension or in compression?
depends on load intensity, if loads are much more large in comparison to self weight of slab it should be in tension
Pls. note that point load is already eccentric. If this point load only is applied at the center of footing then it will definitely create a compression in S15. But, this is not the case! You can try the different probable scenarios and present the responses in spring S15 accordingly.
Point load will induce compression in S15 and moment will induce tension. So without the value of load, moment and length of beam it is difficult to say what will be the final result. Am I right?
