Preface 



FOR more than 25 years we have been engaged in the design 

 and development of reinforced concrete construction. During 

 this period we have had occasion to pubHsh technical data 

 from time to time of interest to the engineer, the architect and the 

 contractor. As a result of these publications we find there is a growing 

 demand for a compilation of data relating to the design of reinforced 

 concrete buildings. A number of comprehensive treatises have been 

 published to meet this demand, but they deal generally with method 

 and theory of design rather than with quantitative results. 



It is not intended, nor is it expected, that this handbook can take 

 the place of any of the excellent textbooks on concrete design or 

 replace the services of the designing engineer. It is hoped that it 

 will supplement the works of reference and as far as possible eliminate 

 the manual labor involved in the repeated application of formulas 

 and diagrams to the determination of the dimensions of a structure. 

 It is the further aim of the book to give under one cover all of the 

 data needed by the busy engineer or estimator in meeting the every- 

 day problems in concrete building design, or briefly to place in his 

 hands designing information that in a measure parallels the familiar 

 handbook of the structural steel manufacturer. 



Until such time as a national building code may be adopted, 

 there will be recognized the impossibility of preparing a thoroughly 

 satisfactory set of reinforced concrete standards so that we have of 

 necessity confined ourselves to stress combinations most widely 

 accepted and within these limits to give a satisfactory range of 

 working values, — values that give the "answer," without further 

 resort to calculation, when the conditions of the problem are known. 



Several of the more comprehensive publications oh reinforced con- 

 crete contain some excellent diagrams that greatly facilitate the 

 designer's work. A few of these diagrams have been incorporated in 

 the present volume and due acknowledgment for their use is hereby 

 made to the work of Messrs. Turneaure & Maurer entitled '* Principles 

 of Reinforced Concrete Construction*' and to "Reinforced Concrete 

 Construction," by George A. Hool, S. B., Professor of Structural 

 Engineering, University of Wisconsin. Further acknowledgment 

 is also made to those members of our organization who so ably 

 assisted in the compilation of the data and to their efforts is due 

 what measure of success may attend the publication of this volume.
