Publisher's Synopsis
As Professor Howe states in his preface this book contains little which is new, but it preserves in compact shape the data needed for designing simple roof trusses, and the principles upon which the strains can be calculated by graphical methods, with their application to simple truss designs in wood and steel. The chapter on strength of materials gives the summary of our knowledge on the strength of wood and steel in all the various ways in which it must be developed in ordinary trusses and the tables at the end of the volume, taken from a steel company's hand book, give the other data needed for computing sizes of pieces for tension, compression and shear in direct or transverse or bearing stress.
After a short chapter on the general points in the design of a truss, the design of a wooden truss for given conditions is taken up in detail. An excellent feature of this chapter is the series of designs for the various Joints and splices in common use where two members of wood or of wood and steel must be joined or a wooden member must be lengthened, including various bearing plates and angle blocks. A similar design for a steel roof truss is quite fully worked out in the following eight pages. The folding plates give the drawings for determining the stresses and showing the details of design of the trusses worked out in the above described chapters.
The book will be very convenient for students and for engineers who are not often called upon for this class of work and wish to save time in looking up data and methods of construction. it is not very extensive, as it is intended to cover only simple trusses and simple connections.
