content: This book, published in 1948, has much useful information. It gives much background on the grading of lumber and the establishing of design stresses. Interestingly, lumber up to the astonishing size of 30 inches by 30 inches is considered. (p. 45).There are the customary beam formulas, as well as ones for assembled wooden I-beams and box beams. There is also data on the design of columns, fastenings, floor systems, plywood, etc. One large table gives loads as a function of beam length and allowable fiber stress. Some worked examples are included, but it would be helpful if there were more of them.
