CONSOLIDATED STEEL CORPORATION 



BETHLEHEM 14-INCH SPECIAL SECTION 

 ROLLED STEEL H-COLUMN 



When columns are required of greater sectional area than the regular 

 sections of H-columns, it is necessary to build a compound section to obtain 

 the desired area. This may be the case in the columns for the lower stories of a 

 high building. 



Additional area may be secured by riveting plates to the flanges of the 

 regular H-columns, but the drilling of the holes for attaching such plate's may 

 be objectionable, on account of the thick metal in the flanges of the heavy 

 H-columns. The 14-inch special section is designed to match the regular 

 14-inch H-columns, and permits the addition of plates, or other shapes, for 

 increasing the area to the desired extent, av oiding the drilling of thick metal 

 in the flanges. 



Dimensions and properties of this special section are given on pages 69 and 

 74. The section is produced by the same rolls and has the same inner contour 

 as the series of 14-inch H-columns on pages 52-53 and 60-61. If the largest 

 regular 14-inch H-column does not provide the required area, the special sec- 

 tion can be used and increased in area to the desired amount, in the manner 

 indicated by Figs. 1-3 on pages 69 and 74. This may be necessary for the heavy 

 columns required in the lower stories of a high building. The regular series 

 of 14-inch H-columns can then be used in the upper stories, where they pro- 

 vide sufficient area. The regular 14-inch H-columns can be spliced to the 

 special section in the usual way. 



Properties of Compound Columns, similar to Fig. 1, are given on pages 

 70-71 and 72-73 and safe loads in the tables on pages 108-109 and 122-123.
