ABSTRACT:

Cover-plate beam-to-column joints are expected to be effective to reinforce the welded flange-bolted web joints with ignorable additional requirement for construction space and are potential to be applied in seismic design of high-strength steel frames. A total of 8 specimens of cover-plate beam-to-column joints with middle columns in steel frames, considering four different combinations of Q345 or Q460 steel beams and Q345, Q460 or Q890 steel columns, were designed according to the Chinese code, and tested subjected to cyclic loads with axial compressions in columns in consideration. The resistance, the stiffness and the ductility of the specimens were analyzed. According to the test results, the cover plates could effectively delay the fracture of the welds and decrease the risks of weld fractures in earthquakes, leading to a satisfactory seismic performance.
