Abstract

For coped beams with welded clip angle connections, block shear is a potential failure mode characterized by web tension fracture underneath the web block of the connections. To investigate the structural behavior and the block shear strength of coped beams with welded double clip angle connections, an experimental study including six full-scale coped steel beam tests with different rotational stiffnesses and aspect ratios of the welded clip angles was conducted. Test results showed that five specimens failed in block shear mode while one specimen did not fail due to the limited capacity of the loading jack but the specimen exhibited obvious block shear type deformation under maximum load. The test results indicated that the block shear strength of the specimens increased with an increasing rotational stiffness of the connections. Moreover, for those specimens with larger aspect ratios of the clip angles, an increase in the block shear strength was found when compared to those with smaller aspect ratios.
