Beam on elastic subgrade
Beam on elastic subgrade
(OP)
I have been given a dessign project to design a concrete grade beam foundation based on ''beam on eleastic subgrade analysis''. I have never performed this analysis. I have been given a soils report with the subgrade modulus. I feel that I understand how to perform the analysis, but I have some questions. The building is one story and supported by masonry bearing walls and steel columns. I plan on using a program named Enercalc. The question I have is how do I analyze a concrete grade supporting a masonry wall and a column offset from the center of the wall approximately 18'' using the beam on elastic subgrade analysis? Any help or comments would be apprciated.

Thanks.

Sounds like you have clayey (A-7-6 or maybe A-6) soils, based on the range given.
The 'actual' subgrade modulus will depend on the degree of compaction and moisture content (relative to 100 percent Standard Proctor) of the subgrade soils, as well as the size and shape of the footing/slab/whatever.

It always seems to be our problem to never get a mat that is a nice geometrical shape, symetrically loaded. I think one of the most interesting areas is combining the frame into the mat structure. Soil structure engineering what a bizarre field. Bigger is definetly better. and yet despite it all there are a pile, excuse the pun, of mats performing well based on winkler springs alone. 'Lets float the thing' so says the architect! ok one to many beers, gotta go.
