      In previous studies, it was shown that the RSFJ brace assembly is prone to elastic buckling for which a new mechanism composed of two telescopic sections was introduced as a remedy to increase the elastic buckling load, ...
    • Designing for Uncertainty 

      Jury, Rob (2021-04-14)
      Structural engineers are familiar with seismic design using a compliance pathway. This typically requires ensuring the provided capacity of structures, expressed as a single value, exceeds the seismic demand, also expressed ...
    • Determining the realistic rotational stiffness of column base connections in steel seismic resisting systems 

      He, Jin Chang Winston; Clifton, Charles; Ramhormozian, Shahab (2021-04-14)
      The New Zealand Steel Structures Standard, NZS 3404, provides an upper and lower rotational stiffness boundary for fixed and pinned column base connections for structural analysis, respectively. These boundaries aim to ...
