BETHLEHEM STEEL COMPANY 



REINFORCED 14" H COLUMNS 



AND 

 SPECIAL COMPOUND COLUMNS. 



When columns are required of greater sectional area than 

 the regular sections of H columns, it is necessary to reinforce 

 the latter 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. In general this is the 

 simplest and most economical method of reinforcement. 

 Dimensions and properties of such reinforced 14" H columns 

 are given on pages 32 and 33 in the table of Reinforced 14" H 

 Columns. 



If it is desired to avoid drilling the thick metal of the flanges 

 of the heavy H columns, for attaching the cover plates, the 

 Bethlehem 14" Special H Section, H14 b, shown below, may 

 be used. Dimensions and properties of this special section 

 are given on the opposite page. This special section is pro- 

 duced by the same rolls and has the same inner contour as 

 the regular series of 14" H columns on page 18, which can be 

 spliced to this special section in the usual way. This section 

 permits the addition of plates, or other shapes, for increasing 

 the area to the desired extent, in the manner indicated by 

 Figs. 1-3 on the opposite page, avoiding the drilling of thick 

 metal in the flanges. Dimensions and properties of heavy 

 columns, made of this Bethlehem 14" Special H Section 

 with cover plates, are given on pages 34 and 35 in the table 

 of Special Compound Columns.
