A pilot study on effectiveness of flow depth as sole intensity measure of tsunami damage potential
(2020-04-22)Current practices have commonly used tsunami flow depth as the sole hazard Intensity Measure (IM) in fragility functions underpinning tsunami damage, loss and risk assessments. Tsunami flow depth is often obtained from ... -
A simple method to predict floor response spectral demands on nonstructural components
(2020-04-22)This paper summarises a newly proposed practice-oriented method to predict elastic floor acceleration response spectra for estimating demands on nonstructural components. The approach builds on previous contributions in ... -
A statistical approach to determine the seismic design parameters in the asymmetric sliding hinge joint using Belleville Springs
(2020-04-22)The design philosophy has changed over the past 20 years in seismic engineering. Structures moved from failing in a controlled ductile manner, to low damage design, to more recently, nearly no damage design (S. Ramhormozian, ... -
A study of current research achievements and challenges on the application of High Strength Steel (HSS) endplates in seismic resisting systems
(2020-04-22)High strength steel is increasing in demand due to economic and mechanical benefits. A typical mechanical characteristic of HSS is that the ductility of the material decreases along with the increase in strength. This has ... -
Advanced FEA assessment of existing concrete floor diaphragms with low-ductility steel reinforcement
(2020-04-22)Diaphragms are primary structural elements which are crucial to the structural stability of buildings. Despite the known deficiencies of diaphragms reinforced with cold-drawn steel mesh, their reliable strength and ... -
An automated wireless-based system for real-time health monitoring of civil infrastructures
(2020-04-22)This paper presents a structural health monitoring (SHM) system based on wireless smart sensor network for real-time condition assessment of civil infrastructures. The system consists of a new wireless smart sensor network ... -
Annexes G and H of the Dutch Seismic Practice Directive NPR9998
(2020-04-22)The province of Groningen in the north-east of the Netherlands is currently experiencing a period of induced seismicity as the result of sustained gas extraction from an underlying gas field. These anthropogenic earthquakes ... -
Concept design of a steel frames post-disaster shelter utilising containers
(2020-04-22)Nowadays, numerous earthquakes happen every year with many resulting in large potential aftershocks. Tents and portable dwellings are widely used as emergency shelters. However, tents can only be used for days or weeks, ... -
Correlation between standard penetration test and shear-wave velocity in Wellington, New Zealand
(2020-04-22)The New Zealand standard NZS1170.5:2004 (amendment 1; Sep 2016; Earthquake actions) recommends seven methods for the determination of site classification as defined in Section 3.1.3.1. The most preferable method is direct ... -
Cybershake NZ v19.5: New Zealand simulation-based probabilistic seismic hazard analysis
(2020-04-22)This paper presents a concise summary of the computational workflow and results of the May 2019 version (v19.5) of probabilistic seismic hazard analysis (PSHA) in New Zealand based on physics-based ground motion simulations ... -
Cyclic tests of an innovative seismic bracing member - multiple U-shaped flexural plates dissipater
(2020-04-22)Following Canterbury earthquake sequence, there has been an increasing interest in development of low-damage structural design using supplemental damping such as the use of metallic dissipaters. In this research, an ... -
Design scenarios for piles in ground subject to liquefaction
(2020-04-22)Seismic shaking and liquefaction with its associated loss of soil strength and ground movements/deformations can be damaging to buildings and their foundations. Understanding ground behaviours and soil-structure interaction ... -
Developing guidelines for the seismic assessment of glazing systems
(2020-04-22)There is an increasing recognition that the seismic performance of buildings will be affected by the behaviour of both structural and non-structural elements. In light of this, work has been progressing at the University ... -
Developing hysteresis curves for the optimised sliding hinge joint with asymmetric friction connections
(2020-04-22)The semi-rigid Sliding Hinge Joint (SHJ) beam-column connection for steel moment resisting frames is a successful low damage system that shows a lot of promise in earthquake engineering. It allows for relative beam-column ... -
Earthquake prone building policy implementation in Lower Hutt
(2020-04-22)Lower Hutt building stock dates back to early nineteenth century, with the majority of older buildings concentrated in central business district and around historic precincts in Jackson Street. Inevitably, buildings built ... -
Earthquake Science at University of Otago
(2020-04-22)Since the establishment of University of Otago’s Earthquake Science Chair in early 2016, our activities have been multidisciplinary, comprising: paleoseismology; earthquake statistics; ground motion simulations; seismic ... -
Earthquake-resilience of storage tanks: using an innovative anchorage system
(2020-04-22)In this study, a new anchorage system has been introduced by employing the recently developed Resilient Slip Friction Dampers (RSFDs) as ductile self-centring hold-downs for liquid storage tanks. This new anchorage mechanism ... -
Element exchange search algorithm for optimal placement of viscous dampers for building structures
(2020-04-22)Optimal design of supplemental dampers efficiently enhances the seismic performance of structures. Existing methods of optimal damper placement design either require a large amount of iteration or can only reliably arrive ... -
