In order to realize the design concept of “strengthened column and weakened beam, strengthened connection joints components” ensure improvement joints’ bearing capacity transfer plastic hinges along beams far away from ends, this paper proposes a new type prefabricated with strengthen-weaken beam-column connection, changes multiple parameters. Six joint models are designed for finite element an...

Many civil applications use square hollow sections (SHSs) as members in beam-column connections which can be vulnerable under cyclic loading. Cyclic loadings from earthquakes, wind, waves and currents affect onshore offshore infrastructure. In addition, these become structurally inadequate through incremental service loads, design/fabrication errors material property degradation over time. Due ...
