CAMBRIA STEEL. 



SIZE OF SINGLE LATTICE BARS TO BE USED WITH 

 LATTICED CHANNEL COLUMNS. 



MAXIMUM LENGTHS OF LATTICE BARS BETWEEN 



FLANGE RIVET CENTERS FOR DIFFERENT 



BAR THICKNESSES. 



Latticing should be so proportioned to resist a shearing stress, 2% of direct 



Inclination of lattice bars to axis of member should not be less than 45 degrees 

 Where distance between lines of flange rivets exceeds 15 inches, if single rivet 

 bars be used, lattice should be double. 



Pitch of lattice rivets along flange divided by least radius of gyration of the 

 member between connections should be less than corresponding ratio of the 

 member as a whole.
