Strength requirements for non-structural components responding nonlinearly under earthquake excitation
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This study develops a practice-oriented method to design non-structural components and their restraints to lower strengths than needed to remain elastic under earthquake ground motion by permitting nonlinear non-structural ...
Incorporating the influence of duration on dynamic deformation capacity in seismic assessment
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The dynamic deformation capacity of a structure is the peak storey drift ratio it can safely withstand without collapsing due to dynamic instability. In a previous study, the authors developed a robust procedure to compute ...
Method for the explicit consideration of ground motion duration in NZS 1170.5
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Recent studies have demonstrated that longer earthquake ground motion duration can reduce structural deformation capacity and increase collapse risk. This study introduces a method to explicitly account for such effects ...
