Similar comparisons with other sizes of the Standard Beams previously 

 rolled by the milts of this country will show that the Bethlehem I-Beams afford 

 an equal carrying capacity but with practically 10 per cent less weight of metal. 



The tables of "Comparison of Bethlehem I-Beams with Standard I- 

 Beams," on pages 37 and 19, show the relation between the two types of beams 

 for all sizes. 



BETHLEHEM GIRDER BEAMS 



Bethlehem Girder Beams from 8 inches to 21 inches in depth, inclusive, 

 have a strength or section modulus and coefficient of strength equal to that of 

 Lsso minimum weight Standard I-Beams of the same depth. The girder beam, 

 however, weighs generally l2 l /2 per cent less than the combined weight of the 

 two Standard Beams, not considering the saving in weight of separators 

 needed for assembling the Standard Beams into a girder. For example, a 

 Bethlehem. 15-inch Girder Beam, weighing 73 pounds per foot, has a coefficient 

 of strength of 1,256,000. Two Standard 15-inch I-Beams, each weighing 42 

 pounds per foot, have a total coefficient of strength of 1,256,600. Thus, for 

 equal depth and coefficient of strength, the girder beam weighs 11 pounds per 

 foot less than the two Standard Beams. This is a saving of 13 per cent in 

 weight, not including separators, which would add at least 2 ^pounds per foot 

 more to the weight of the assembled girder. In this case a total saving of 1 6 

 per cent in weight is afforded by the Bethlehem Girder Beams, besides the 

 saving in the cost of assembling the Standard Beams into a girder. 



The tables of "Comparison of Bethlehem Girder Beams with Girders of 

 Standard Beams," on pages 36 and 48, show the relation between the two 

 types of beams. 



The tables on pages 36-37 and 48-49 furnish a key for the comparison of 

 Bethlehem I-Beams and Girder Beams with Standard Beams. A framing 

 plan for Standard Beam shapes may be easily revised for the use of Bethlehem 

 Beam Sections. In general, no rearrangement of the plan will be necessary 

 and no recalculation will be required, except to select the proper Bethlehem Sec- 

 tions which are equivalent in strength to the Standard Beams and Girders. 



BETHLEHEM ROLLED H-COLUMNS 



All column shapes having the same section number are made by the same 

 rolls. Thus, the 14-inch H-Columns, comprising all the weights and variations 

 in size of sections shown on pages 52-53 and 60-61 are from the same rolls, fur- 

 nishing a series of rolled columns of similar shape. Columns can thus be selected 

 of the proper areas to suit variations of load, affording a wide range of sizes from 

 the same rolling and insuring prompt delivery. 



To provide for splices and connections is the only fabrication required for 

 these rolled columns. In the case of columns with thick metal the holes require 

 drilling, which can be done economically with a multiple drill. The saving in 

 cost of fabricating the rolled column as compared with a built-up riveted 

 column is a great advantage in favor of the solid rolled shape. Sections can be 

 spliced to make a practically continuous column, and connections are easily 

 made in the most approved manner of the best structural practice. All sur- 

 faces of the column are accessible for painting.
