“…Traditionally, angles with a single bolt are not considered to provide any rotational restraint [5] and are treated as pin-ended columns. In reality, members with more than one bolt in the end connection scan be considered as those with intermediate level restraint.…”

Experimental data on single angle compression members with single-and double-bolt end connection patterns is used to develop adjustment factors for effective buckling lengths. Connection length and clamping effect parameters are proposed and evaluated based on test data. Results from a total of 24 equal leg test angles with single-and double-bolts are used. Slenderness ratios considered ranged from 158 to 312. Angle sizes ranged from 1½" x 1½" x⅛" to 3½" x 3½" x ¼". Estimated connection lengths were about 12.5% of the member length for single-bolt joints and24.7% for double-bolt joints. Computed effective length factors ranged from 0.753 to 0.875. Results seem to indicate that it is possible to define and calculate connection length of a lattice tower angle member. Suggestions for incorporating connection length issues in routine designs are made.
