A displacement-based design method of low-damage dual systems with hysteretic and nonlinear viscous energy dissipation
(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. ... -
Area Ratio or Volumetric Ratio: Which is better for quantifying the confinement of concrete?
(2023-04-19)Confinement of concrete helps in improving ultimate strain of concrete. This increase depends on amount of transverse reinforcement in the vertical member. While the need for 1350 hooks in transverse reinforcement is ... -
Assessment of lateral spread potential used smeared strengths of liquefied/non liquefied soils
(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 ... -
Case Study for Seismic Assessment of an Existing Asymmetric non-prismatic Unique Reinforced Concrete- encased Steel Plate Column in Wellington
(2023-04-19)This case study presents a tailored approach to assessing a high-rise building in the Wellington CBD constructed primarily from reinforced concrete encased steel frames. This construction is rare in New Zealand, and it is ... -
Deformability of lap splices in RC structural walls
(2023-04-19)Severe structural damage associated with lap splices located near the foundation of reinforced concrete (RC) structural walls has been recorded in the field after recent major earthquakes in Chile, New Zealand, and Taiwan. ... -
Design Considerations for Buckling Restrained Braces in Timber Frames Subject to Out of Plane Deformations
(2023-04-19)The introduction of using steel buckling restrained braces (BRBs) has proven to greatly improve the in-plane seismic performance of timber structures. However, little is understood about the performance of BRBs subject to ... -
Design of Mixed Angle Screw CLT Hold-Down Connections to New Zealand Timber Standards
(2023-04-19)Mixed angle screws provide a strong, stiff, and ductile hold-down solution for high-capacity Cross Laminated Timber (CLT) shear walls. Timber is an inherently brittle material and most inelastic responses in timber structures ... -
Displaced But Not Moved: Performance-Based Foundation Design
(2023-04-19)Improved understanding of seismicity within New Zealand and globally has led to an increase in seismic hazard for many locations. High seismic acceleration demands (e.g. >1g) for buildings and infrastructure have led to ... -
Earthquake Protection of Residential Buildings: New Resilient System for Light Timber Framing
(2023-04-19)In NZ, similar to other countries, residential houses are mostly constructed using light timber framing. The common seismic solutions available in the market for such low-rise buildings are based on yielding of sacrificial ... -
Establishing the Transverse Load Capacity of a Timber-framed Classroom Block
(2023-04-19)In 2013, longitudinal testing of single storey timber-framed classroom blocks was initiated by the Ministry of Education and completed by BRANZ to better understand the seismic resilience of timber-framed buildings within ... -
Liquefaction induced kinematic loads on piles and inertia loads - literature review and recommendations for design
(2023-04-19)Earthquake shaking can cause soil liquefaction in certain types of soil. The associated loss of soil strength and stiffness coupled with any lateral ground movement can be damaging to buildings and their foundations. Pile ... -
Method for the explicit consideration of ground motion duration in NZS 1170.5
(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 ... -
Performance assessment of shallow founded buildings on liquefiable soils
(2023-04-19)In evaluating foundation options for sites featuring liquefiable soils, shallow raft foundations may remain a suitable and preferred solution, provided the seismic performance can be demonstrated to be adequate. In evaluating ... -
Performing Structural Assessment using Acoustic Measurements
(2023-04-19)Natural hazards, such as earthquakes, could be catastrophic. One challenge that society faces is how to provide a rapid and accurate evaluation of the structural damages after the events. Traditional visual inspection is ... -
Seismic Performance Comparison of New Zealand and Japanese Concrete Moment Frames
(2023-04-19)Observations of the performance of reinforced concrete (RC) buildings after the 2016 Kumamoto earthquake in Japan showed buildings designed using Japanese standards resulted in less damage and downtime compared to buildings ... -
The next generation of drywall construction for low-damage design
(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 ...
