Chevron Buckling Restrained Brace Frame Seismic Behaviour Considering Out-of-Plane Effects
(New Zealand Society for Earthquake Engineering, 2023-04-19)
This project evaluates the behaviour of buckling restrained braces (BRBs) in a chevron configuration considering IP and OOP frame deformations using software capable of second-order inelastic frame analysis. Initially a ...
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 ...
Optimum service and seismic structural protection with adaptive dampers and base isolators for immediate occupancy after the earthquake
(New Zealand Society for Earthquake Engineering, 2023-04-19)
To improve serviceability of important civil structures during seismic action, base isolators and dampers need to perform with high efficiency independent of the ground shaking level. In service and seismic actions, base ...
Assessment of lateral spread potential used smeared strengths of liquefied/non liquefied soils
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Liquefaction-induced lateral ground displacements (lateral spread) are typically assessed using empirical methods where a continuous weak (liquefied) layer is expected. These methods are not appropriate for variable fill ...
The next generation of drywall construction for low-damage design
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Low-damage structural systems that can withstand large earthquakes with no structural damage, or localised damage in pre-defined fuses, have become commonplace in the past one to two decades. These systems however, generally ...
Comparison of optimal versus a convenient distribution method of viscous damper design
(New Zealand Society for Earthquake Engineering, 2023-04-19)
A simple and convenient method often adopted by practicing engineers designing supplemental viscous dampers to a building is to calculate damping coefficients of viscous dampers corresponding to a desired added damping ...
Numerical Investigation of Australasian Cold-Formed Steel strap-braced walls under lateral and vertical load
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Cold-Formed Steel (CFS) gained popularity in residential buildings due to its dimensional accuracy, lightweight, resistance to shrinking and creeping, durability, low embodied carbon and CNC manufacturing abilities. The ...
Societal Expectations for Functional Recovery of Primary and Secondary School Buildings
(New Zealand Society for Earthquake Engineering, 2023-04-19)
In the ongoing investigation of functional recovery requirements, the spectrum of functional requirements for different facility types is necessary to ensure buildings are designed, constructed, and maintained to meet ...
A prescriptive method for the design of new steel moment frame structures with supplemental damping
(New Zealand Society for Earthquake Engineering, 2023-04-19)
This paper presents a prescriptive method for the design of new steel moment frame structures with supplemental damping using fluid viscous dampers. The prescriptive method uses Modal Response Spectrum Analysis (MRSA) ...
A displacement-based design method of low-damage dual systems with hysteretic and nonlinear viscous energy dissipation
(New Zealand Society for Earthquake Engineering, 2023-04-19)
In 2019, a large shaking-table test was performed for a full-scale two-storey low-damage concrete wall building. The test building comprises unbonded post-tensioning (UPT) rocking walls and perimeter frames in both directions. ...
