Flexural testing for composite members with bolt-connected steel angles

Investigation on mechanical behavior of steel angle frame reinforced concrete beams under torsion

“…A series of studies have investigated the compressive, [4][5][6] flexural, [7][8][9] and seismic [10][11][12] properties and the confining mechanism [13] of SARC members, but studies on torsional behavior of SARC are still relatively limited. On the other hand, complex and irregular structures continue emerging due to the special needs of architectural functions and appearances, resulting in the significant torsional moments on structural elements, especially bridges curved in space, corner columns in frame, and spandrel beams in buildings, [14,15] which explains why the torsional performance of the structure cannot be ignored.…”
