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 ...

Steel flush endplate beam-column connections behavior is commonly described by the moment-rotation, M-φ, relationship, which characterized two essential terms; resistant moment, Mj, Rd, and initial rotational stiffness, Sj, init. A great amount of concerted effort has been invested worldwide to either experimentally or analytically describe these properties due geometrical material variations. ...

Abstract Currently, many buildings are constructed with precast concrete methods. However, they still use the cast in-situ method, especially for beam and column connection system where there some obstacles in casting process possibility of installing reinforcement bars on site not following design. Hence, is potential structural failure that part connection. To reduce constraints, it proposed ...
