Experimental tests on bolted steel angles in compression with varying end supports

Research output: Contribution to journalArticlepeer-review


The paper presents the detailed test setup and results of a test series on bolted single steel angles in compression with varying end support conditions and slenderness ratios. For all tests FEM-calculations were done, which are also presented. In total 27 specimens with one-bolt and two-bolt connections with and without preload are tested. Three different boundary conditions on both ends are investigated: Boundary condition 1 (BC1) is a clamped support. BC2 is a knife edge support that allows only for rotations about the axis parallel to the connected leg. BC3 is a fully hinged support. In addition to the results of the member tests, imperfection measurements and results of material tests are presented in order to carry out the FEM-calculations and to allow for comparison with current design standards.
