Accounting for the Influence of Intrinsic Soil Properties and State Variables on Liquefaction Triggering
(2023-04-19)Current simplified liquefaction triggering procedures are limited in their ability to capture the effects of intrinsic properties (grain size, mineralogy, grain shape, etc.) and the state properties (stress state, void ... -
Achieving earthquake-safe buildings – an educational initiative for developing nations
(2023-04-19)Building departments in developing nations have a poor track record of achieving earthquake-safe new buildings. Many buildings, within their jurisdictions are not expected to perform well in medium- to high-intensity ... -
Advanced seismic design of concrete-to-concrete structural connections
(2023-04-19)Seismic strengthening of concrete buildings and bridges may require the addition of new concrete members or overlays. One way of connecting new concrete to existing concrete is using post-installed rebar (PIR) connections. ... -
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 ... -
Avoiding moat wall pounding of base-isolated buildings using D3 viscous dampers
(2023-04-19)Base-isolated buildings are typically important facilities expected to remain functional after a major earthquake. Seismically isolated buildings can experience large displacements at the isolation level during strong ... -
Base isolated building preformance and the impact of the national seismic hazard model
(2023-04-19)The NZSEE/MBIE recently released seismic design guidelines aiming to provide a more consistence design performance of base-isolated buildings in NZ. This paper confirms the superior performance of base-isolated buildings ... -
Behaviour of Unreinforced R.C. Beam-Column Joints Under Bidirectional Loading
(2023-04-19)Modern building codes for reinforced concrete (RC) frame structures in areas susceptible to earthquakes prescribe detailing requirements for the beam-column joint to prevent shear failure and subsequent loss of gravity ... -
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 ... -
Chevron Buckling Restrained Brace Frame Seismic Behaviour Considering Out-of-Plane Effects
(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 ... -
Comparison of optimal versus a convenient distribution method of viscous damper design
(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 ... -
Cyclic behavior of older concrete columns reinforced with high-performance fiber reinforced cementitious composites
(2023-04-19)Many older existing reinforced concrete (RC) buildings were designed without considering seismic loads. In such buildings, columns may be the most vulnerable element because they generally have insufficient reinforcement ... -
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 ... -
Developing Construction 4.0 transformation of Aotearoa New Zealand's construction sector
(2023-04-19)Aotearoa’s construction industry reached over $20.5 billion in 2019 and it became the fourth largest workplace in the year ended June 2021, significantly contributing to New Zealand’s economy. However, it has long been ... -
Development, verification, and validation of a buckling-fatigue steel material model
(2023-04-19)Currently, there are limited constitutive models available in finite element analysis packages that reliably capture the coupled effects of bar buckling and fatigue. However, such a model is needed for reliable estimation ... -
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 ... -
Dynamic analysis of tall reinforced concrete walls designed with minimum vertical reinforcement
(2023-04-19)Analysis of tall walls subjected to the earthquake ground motions highlights the amplified dynamic moment response at the mid-height due to the higher mode effect. The amplified moment demand may result in unexpected ... -
Dynamic Behaviour of Interlocking Plastic-block Structure Using Shake Table
(2023-04-19)Severe damage was caused by the earthquake, primarily to non-engineered structures in rural areas. Structures including roads, bridges, buildings and railroad tracks all suffered catastrophic destruction as a result of ...
