Excerpt from Graphical Handbook for Reinforced Concrete Design
In this work, there is presented a series of plates, showing graphically, by means of plotted curves, the required design for slabs, beams, and columns, under various conditions of external loading, together with practical examples explaining the method of using each plate. The design for most of the more commonly occurring forms of reinforced concrete construction may be ascertained directly from these plates, without performing any of the computations ordinarily required. While practically nothing more than an inspection of the plates is needed to select a design for given conditions, nothing is sacrificed in the way of flexibility by the graphical method, but, on the contrary, an exceptionally wide range of choice is afforded as to the relative proportions of steel and concrete to be used.
The unit stresses prescribed by the Building Code of New York City have been adopted throughout, as a standard, and it is believed that the methods here used are those sanctioned by the best practice at the present time.
This book is expected to appeal chiefly to those architects and engineers whose work in reinforced concrete design is intermittent in its nature, and does not warrant the steady employment of a "concrete engineer." In such offices, the use of a graphical handbook should render it unnecessary to call in expert assistance to solve the majority of problems ordinarily encountered.
