• A new unbiased metamodel method for efficient reliability analysis 

      Xue, Guofeng; Dai, Hongzhe; Zhang, Hao; Wang, Wei
      Published 2017-07-01
      Metamodel method is widely used in structural reliability analysis. A main limitation of this method is that it is difficult or even impossible to quantify the model uncertainty caused by the metamodel approximation. This ...

    • A new maximum entropy-based importance sampling for reliability analysis 

      Dai, Hongzhe; Zhang, Hao; Wang, Wei
      Published 2016-11-01
      Importance sampling can be highly efficient if a good importance sampling density is constructed. Although the parametric sampling densities centered on the design points are often good choices, the determination of the ...

    • Recent developments on the Component Method 

      Rasmussen, Kim; Zhao, Xianzhong; Yan, Shen; Dai, Liusi; Zhu, Chen; Jiang, Luli
      Published 2019-09-16
      The Component Method is well established and incorporated in Part 1.8 of Eurocode3 for the design of connections of steel frameworks. It is primarily intended to provide the elastic joint stiffness, although Part 1.8 ...

    • Generalised Component Model for Structural Steel Joints 

      Zhu, Chen; Rasmussen, Kim; Yan, Shen
      Published 2019-02-01
      This paper presents a generalised component model for structural steel joints that extends the Component Method to the post-ultimate and post-fracture ranges. In this approach, a tri-linear spring model was developed for ...

    • Full-range behaviour of semi-rigid steel connections 

      Zhu, Chen; Jiang, Luli; Rasmussen, Kim; Yan, Shen; Zhang, Hao
      Published 2018-12-01
      The paper summarises recent research programs undertaken at the University of Sydney on determining the full-range behaviour of steel connections including post-peak softening and fracture. The overall context of this work ...
