Experimental proof of the effectiveness of timber panels in the seismic retrofit of URM buildings
(2023-04-19)Recently there has been a growing interest by both academia and the industry in the possibility of using timber as a strengthening material for the seismic retrofit of unreinforced masonry (URM) buildings. This possibility ... -
Experimental study on structural performance and damage characteristics of repaired flexural RC members
(2023-04-19)Understanding the expected seismic performance recovery of repaired members is important to make an effective recovery plan for damaged buildings. In this research, three RC beam and three RC wall specimens were subjected ... -
Feasibility of capacity spectrum method for analysis of low damage structural systems with friction connections
(2023-04-19)The use of friction connections for low damage design of new structures has been increasing over the past few years. These connectors have a high energy dissipation ratio and are relatively economical to fabricate and ... -
Field miniature prototype development and pilot project design of subsurface compacted Rubble Raft (SCRR)
(2023-04-19)Subsurface Compacted Rubble Raft (SCRR) is a patented wide-area ground improvement solution that focuses on solving severe liquefaction hazards. SCRR technique directly targets the liquefaction layers by constructing a ... -
Finite Element Convergence Study of the Asymmetric Friction Connection (AFC) in the Optimised Sliding Hinge Joint (OSHJ)
(2023-04-19)The Optimised Sliding Hinge Joint (OSHJ) is a cost-effective, low damage seismic resisting beam-column connection developed for Moment Resisting Steel Framed (MRSF) buildings. The OSHJ is the optimised version of the ... -
Framework Development for a Hybrid Geotechnical-Geospatial Liquefaction Assessment Model
(2023-04-19)Liquefaction assessment can be performed using various bodies of knowledge, each with an associated accuracy based on the data involved. Liquefaction assessment models based on directly measured subsurface geotechnical ... -
GeoNet’s Shaking Layer Tool: Generation of near-real time ground shaking for post-event response
(2023-04-19)Information on ground shaking following an earthquake is important for many applications from emergency response, engineering assessments, infrastructure management, insurance claim estimation and research. GeoNet, along ... -
High capacity glued-in rod connections in Cross-Laminated Timber (CLT) structures
(2023-04-19)Glued-in rods are efficient and high-capacity connections for achieving high-strength connections in new timber structures and reinforcing existing timber buildings. With the emergence of cross-laminated timber (CLT) and ... -
How to assemble elemental damping?
(2023-04-19)An elemental damping model has recently been proposed as an alternative to the Rayleigh damping model to avoid spurious damping forces during inelastic seismic response. It has shown great potential because it has the ... -
Influence of remedial ground densification on seismic site amplification
(2023-04-19)While the capability of remedial ground densification techniques to mitigate the adverse effects of liquefaction has been widely investigated in recent decades, the characterization of ground motion amplification in the ... -
Innovative Resin Injection Ground Improvement to Build Up Seismic Resilience of Existing Water Structures
(2023-04-19)The existing Wellington Water’s Waterloo Water Treatment Plant (WTP) in Wellington, New Zealand is an important post-earthquake facility for the Wellington region. The WTP is founded on soils prone to liquefaction and ... -
Innovative Retrofit Solution for Exterior Unreinforced R.C. Beam-Column Joints
(2023-04-19)Most reinforced concrete (RC) frame buildings in New Zealand constructed pre-1960s have unreinforced beam-column joints. Following MBIE/NZSEE assessment guidance, the seismic performance of RC frames with unreinforced ... -
International alignment and update of the New Zealand earthquake intensity scale
(2023-04-19)The New Zealand Modified Mercalli intensity (MMI) scale was last revised in 2008. Even so, the scale's lack of specificity on New Zealand's structures for MMI>8 intensity levels has made it difficult to assign values for ... -
Investigating the effect of stiffness on the seismic performance of RC structures
(2023-04-19)This study investigates the correlation between stiffness and the seismic performance of RC structures. Structural performance was compared for buildings affected by four different earthquakes, Tokachi-Oki (1968), Chile ... -
Learning Importance Sampling Distributions via Normalizing Flows to Estimate Rare-Event Failure Probabilities
(2023-04-19)Engineered systems are typically designed to be robust and have very low probabilities of failure. However, developing accurate estimates of these probabilities can be challenging given the complex (and typically nonlinear) ... -
Lincoln University Waimarie building: An application of friction damping devices with recentring for low damage design
(2023-04-19)The experience from Christchurch and Kaikoura seismic events demonstrated well that the ‘life safety’ criteria is not sufficient to protect the community from earthquake impact. Currently, the community expects more measures ... -
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 ... -
Low Damage Wall To Floor Connections For Seismic Resilient Timber Structures
(2023-04-19)Rocking timber walls provide superior seismic performance in comparison with conventional light timber structures. Nevertheless, there is an uplift movement at the base of the wall that is translated as vertical displacement ... -
