One hundred and ninety seven steel single angles loaded through two bolts in one leg were tested for their compressive strengths. They included five different sizes (76 x 51 x 6.4, 127 x 76 x 6.4, 64 x 64 x 6.4, 64 x 64 x 4.8, and 76 x 76 x 6.4 mm) and slenderness ratios varying from 69 to 201. The gauge distances were varied from the minimum to the maximum possible value for each size of angle. The effect of the connection type (snug tight and pretensioned) was also investigated. The effect of the width of the connected leg (long leg connected versus long leg out) was studied. All experimental failure loads were compared to CAN/CSA-S16.1-94 (Limit States Design of Steel structures), CSA-S37-94 (Antennas, Towers and Antenna Supporting Structures). It was shown that the S16.1 standard was extremely conservative while the S37 standard gave more realistic estimations. Variation of yield stress across the cross-section was determined for forty-two stock lengths of angles. Although the nominal yield stress was 300 MPa for all the specimens, the yield stresses determined ranged between 311 and 479 MPa with an average value of 363 MPa. Thirty-nine different stock lengths of steel angles were tested for the distribution of residual stresses. This distribution, however, did not show any specific pattern.Dept. of Civil and Environmental Engineering.
