METHOD OF SELECTING 



BETHLEHEM ROLLED H-COLUMNS 



FOR BUILDINGS 



EXAMPLE 



For illustration, the interior columns of an actual 16-story building are 

 taken as an example. The story heights and the loads on the columns are 

 given in the following table: 



Columns for buildings are usually selected in lengths of two stories. By 

 inspection of the tables of safe loads for H-columns, it is found that no columns 

 smaller than 14-inch H-sections have sufficient capacity for the lower stories. 

 From the tables on pages 100-101 or 114-115 the 14-inch H-columns required are 

 then selected for the lower stories; and from the tables on pages 102-107, or 

 116-121, the 12-inch, 10-inch and 8-inch columns are selected for the upper 

 stories. 



All the sizes of columns, as selected and given in the above table, from 

 the basement to the 9th story inclusive, are obtainable from the same rolls at 

 at a single rolling. 



Where there is no limitation as to the size of the column the largest dimen- 

 sion column having the required capacity will be the most economical.
