Abstract: A testing program involving steel beam-to-column web moment connections was recently conducted at Lehigh University. The connections studied had the beam attached to the web side of a wide-flange column by different combinations of bolting and welding with the beam loads tending to bend the column about its weak axis. Four subassemblages each consisting of a W14x246 column and a W27x94 beam on one side of the column only were tested to ultimate under simulated static loading conditions by applying a load to the beam while the column was experiencing an axial load. Presented is a description of the testing program, load versus deflection plots and a description of the failure modes of the four connections. Conclusions are drawn regarding the performance of the assemblages.
