THE columns of a building are of greater importance than any other parts of the construction. At first blush, it may strike one that all parts of a building are equally important; but there is a double, or, in fact, a triple duty on the columns of a building, and hence the stability and integrity of a structure depends in a larger degree on the columns than on any other elements of a structure.
The object of the present paper is to show a method of finding the areas of reinforcements in a rectangular member subjected to bending and compression when the stresses are known.
The great rise in the cost of bricks and in the wages of the building trades workmen, added to the general scarcity of operatives in certain of the essential crafts of the building industry, impelled the various municipalities throughout the Netherlands to adopt alternative and supplemental methods of house building. The City of Amsterdam experimented upon a somewhat considerable scale with new materials and methods, and with the application of mechanical contrivances. More than 40 different systems of concrete building were in the first instance carefully considered and elaborate tests were carried out by the officers of the municipality. As a result of these experiments
the municipality decided to adopt for a thorough and practical test 10 of these various systems of concrete building and seven building firms were entrusted with contracts for the erection of 900 dwellings, in all, upon one of the extensive housing estates acquired by the city authorities.
