Riassunto

Excerpt from The Theory of the Flexure and Strength of Rectangular Flat Plates Applied to Reinforced Concrete Floor Slabs

In reviewing the history of every type of structural work, we find the designing engineer influenced in his first attempts at any new type of structure by his knowledge of the practical forms of con struction with which he is already familiar. In fact until very recent times precedent was the engineer's sole guide. It was to be expected therefore that the pioneers in concrete-steel construction should follow and closely imitate timber and structural steel con struction. In following this type, the idea has been to build up the structure as a whole by assembling and joining together a number of independent elements or units: whereas concrete, with or without reinforcement, is a kind of material that is best suited by its nature to construction in monolithic form. But when the attempt has been made to treat such structures theoretically, preconceived ideas have led to the effort to treat them by analysing them into separate members and computing the strength of these arbitrarily selected units, assumed to act independently as they do in steel structures. Such treatment has led to errors of as much as two or three hundred percent in the computation of slabs with two way reinforcement supported on four sides, and to errors of four hundred percent in case of continuous fiat slab construction such as occurs in the mush room system.

When we consider the fact that fire losses in Canada and the United States amount each year to half a billion dollars, and that the question of commercial economy determines whether buildings shall be built of fireproof and incombustible materials such as rein forced concrete, or of inflammable materials such as are used in timber construction, it is at once evident how important it is to the general public to be able to determine on theoretically correct principles whether safe fireproof buildings can be built at approximately the same or less cost than combustible ones. In case of any uncertainty on this question, the designer is compelled for safety to employ materials in such lavish amounts as to render cost prohibitive.
