How practitioners can work together to achieve better seismic performance outcomes for buildings and infrastructure
(2021-04-14)A key recommendation from the Canterbury Earthquakes Royal Commission was that there should be “greater cooperation and dialogue between geotechnical and structural engineers” to help improve the seismic performance of ... -
Impact of Canterbury earthquakes on the evolution of earthquake geotechnical engineering practice
(2021-04-14)Earthquake geotechnical engineering practice has evolved in New Zealand during the past 40 years. The 2010-2011 Canterbury earthquakes provided significant impetus to the research and practice. Early evolution commenced ... -
Incorporating the influence of duration on dynamic deformation capacity in seismic assessment
(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 ... -
Influence of damping models on nonlinear seismic response of a base isolated building
(2021-04-14)This paper discusses the effect of different damping models on nonlinear seismic response of a 8 storey 2D base isolated (BI) building: (1) Rayleigh damping proportional to the mass and initial stiffness matrices, (2) ... -
Investigating the impact of design criteria on the expected seismic losses of an office building
(2021-04-14)Low Damage Seismic Design (LDSD) guidance material being developed by Engineering NZ is considering a design drift limit for multi-storey buildings of 0.5% at a new damage control limit state (DCLS). The impact of this new ... -
Investigation of the Plastic Drift Capacity of RC Frames with Beam-Column Joint Failure
(2021-04-14)MBIE/NZSEE guidelines have various methods to assess existing buildings, of which Displacement Based Assessment (DBA) is one. This paper reports on the application of DBA to reinforced concrete (RC) frames where beam-column ... -
Liquefaction Assessment of Reclaimed Land at CentrePort
(2021-04-14)The 2016 Mw7.8 Kaikōura earthquake caused widespread liquefaction in the port of Wellington (CentrePort), New Zealand which produced substantial lateral ground movements along with global and differential settlement. ... -
Liquefaction Risk Analysis of Native and Reclaimed Soil Deposits in Central Wellington
(2021-04-14)Following the 2016 Kaikōura earthquake, severe and damaging liquefaction was observed at the port of Wellington in areas of reclamation fills built at the beginning of or mid 20th century. However, little or no damage was ... -
Monitoring of lateral stiffness changes for a real building using hysteresis loop analysis
(2021-04-14)The BNZ building in Wellington, New Zealand was significantly damaged, and eventually demolished, due to the cumulative impact of three main earthquakes between 2013 and 2016. Although the building was equipped with a set ... -
Numerical modelling of a concrete wall-steel frame building
(2021-04-14)Buildings that use concrete walls together with steel frames have become increasingly common in Christchurch, with around 35% of post-earthquake buildings using such mixed-material structural systems. This rapid shift in ... -
Performance Comparison of Buckling-Restrained Braces and Friction Dampers Adopted for Retrofit of an Existing RC Frame Building Using Performance-Based Retrofit Procedure
(2021-04-14)This paper presents a performance-based retrofit approach for designing and performance comparison of Buckling -Restrained Braces (BRBs) and Friction Dampers as retrofit strategies for RC frame buildings. An overview of ... -
Seismic behaviour of a non-linear structure with passive D3 viscous damper
(2021-04-14)Passive Direction Displacement Dependent (D3) viscous damper is a next generation of the conventional viscous damper could provide damping force in any desired quadrant to provide wanted damping hysteresis loop. This ... -
Seismic Design and Analysis of a Medium Density Residential Building
(2021-04-14)There is an increasing recognition that good seismic performance requires not only checks on life-safety but also limitation of damage, disruption and losses. In light of this, several proposals are currently being developed ... -
Seismic Strengthening Auckland's Waterfront
(2021-04-14)Seawalls were constructed in sections between 1879 and 1925 to form Quay Street on the waterfront of Downtown Auckland. These seawalls have essentially remained structurally unchanged since they were first constructed and ... -
Seismic upgrading of friction-damped steel frames integrated with self-centring devices
(2021-04-14)Conventional friction-based damping devices are known for their large energy dissipation capacity and economic benefits compared to other seismic mitigation systems. These devices have been implemented in many practical ... -
SESOC Software – Seismic Design Tools
(2021-04-14)SESOC has accumulated a number of structural software design programs, over time, which we actively maintain/enhance, also on occasion developing a new tool for the benefit of our members – and the NZ design fraternity. This ... -
Shake table testing of fire sprinkler piping systems typical of New Zealand practices
(2021-04-14)An automatic fire sprinkler piping system requires an intricate piping network to feed individual sprinklers spread across the plenum space. In practice, this elaborate piping network is braced against seismic demands ... -
Simplified numerical modeling of reinforced concrete columns with smooth rebars
(2021-04-14)Pre-1970s concrete buildings in New Zealand were commonly constructed with smooth longitudinal reinforcing bars. The NZSEE guideline for the seismic assessment of existing buildings (NZSEE C5) recognizes that the seismic ... -
Strength requirements for non-structural components responding nonlinearly under earthquake excitation
(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 ... -
