- Abstract
In reinforced concrete structures there is no commoner problem than the design of an ordinary concrete column footing, and yet there are no parts of the structure more difficult to submit to a reasonably approximate method of calculation. The problem of the determination of the stresses in a thick slab, carrying a concentrated load at its centre and uniformly supported over its base, has never been worked out mathematically, and the best the engineer can do is to use some rough approximate method which appears to give results that lead to a safe design as tested by experience. Unfortunately the books are by no means in agreement as to what this approximate method should be, and the 27 tests recorded here have been made on small footings in the University Laboratory with the object of gaining a little more information about a difficult subject.
