“…For S / B > 1.0, with a smooth footing base, the present ξ γ values are found to be only marginally lower as compared with the solution of Mabrouki et al . On the other hand, for S / B < 1.0, the values of ξ γ computed by Mabrouki et al have been found to be significantly higher; it should be mentioned that for rough footings, the values of ξ γ were also found to be even greater than the upper bound solution of Kumar and Kouzer .…”

“…It needs to be mentioned that both the footings are loaded to failure simultaneously. It is, however, known from the solution available in literature that in case only one footing is loaded to failure, the increase in the ultimate bearing due to the interference becomes smaller than that in case both the footings are loaded to failure simultaneously.…”

“…From the available literature , it is understood that the ultimate bearing capacity of a group of two interfering footings placed on sandy media becomes always greater than that for a single isolated footing. The different existing theories, on finding the effect of footings' interference on their ultimate bearing capacity, are based on the limit equilibrium approach , the method of the stress characteristics , the upper bound finite elements limit analysis , and the Fast Lagrangian Analysis of Continua (FLAC) . Except the recent analysis of Mabrouki et al , which is based on FLAC and is meant for both smooth and rough footing base, all the other existing theories in literature on the interference of footings deal only with the rough footing base.…”

SUMMARYA rigorous lower bound solution, with the usage of the finite elements limit analysis, has been obtained for finding the ultimate bearing capacity of two interfering strip footings placed on a sandy medium. Smooth as well as rough footing-soil interfaces are considered in the analysis. The failure load for an interfering footing becomes always greater than that for a single isolated footing. The effect of the interference on the failure load (i) for rough footings becomes greater than that for smooth footings, (ii) increases with an increase in f, and (iii) becomes almost negligible beyond S/B > 3. Compared with various theoretical and experimental results reported in literature, the present analysis generally provides the lowest magnitude of the collapse load.

“…Soil is considered by the engineer as a complex material produced by the weathering of the solid rock. Soil is the most important material which is in use for construction of civil engineering structures (Kouzer and Kumar, 2010). Among all parameters, the bearing capacity of soil to support the load coming over its unit area is very important.…”

Most Finite Element packages provide means to generate meshes automatically. However, the user is usually confronted with the problem of not knowing whether the mesh generated is appropriate for the problem at hand. Since the accuracy of the Finite Element results is mesh dependent, mesh selection forms a very important step in the analysis of isolated and combined footing pad foundation. SAFE is an ultimate tools use in the design of concrete floors and foundation system, hence provide a suitable means for the user. From framing layout all the way through to detail drawing production, SAFE integrate every aspect of engineering design which are in one process easy and intuitive environment. SAFE provides unmatched benefits to the engineer with its truly unique combination of power, comprehensive capabilities, and ease-of-use. In the context of this research, we have plotted graphs showing the relationship between the nodes and displacement with the stress patterns as generated from the software. It is understood from the graph that multiple elements in the process of meshing will make the footing to be at equilibrium. The research also carry the shape deformed diagram which shows the deformation of the footing due to the impose load (stress) on the footing, it also give the bending moment diagram of the footings. The basic structure and analysis of the single and double pad footing foundations have been designed using Finite Element Analysis (FEA) with the failure planes being considered. The results obtained, it is assumed that FEA is an ideal design method that breaks foundation design into basic elements and nodes that shows the action of the loading on the footings.
