Experimental Testing of Brittle RC frames Strengthened by RSFJ-toggle bracing system
(2024-04-09)This paper investigates the performance of the new retrofitting system, consisting of self-centering damper resilient slip friction joint (RSFJ)-toggle bracing system, as a global retrofitting method for deficient RC frame ... -
Exploring resiliency between different steel lateral systems for new construction
(2024-04-09)It is known that while base level, code compliant structural designs produce buildings with a low likelihood of collapse, there is little guarantee that buildings will remain functional following moderate to severe ... -
Finite Element Method Analysis of Reinforced Concrete Exterior Beam-Column Joint Structures Subjected to High Varying Axial Forces
(2024-04-09)Large variation of axial forces in columns in the lower stories of a high-rise reinforced concrete buildings during a severe earthquake can cause significant changes in the column-to-beam strength ratio in the exterior ... -
Finite Element Modelling (FEM) of the Asymmetric Friction Connection (AFC) with Belleville Springs (BeSs): challenges and ongoing developments
(2024-04-09)The Sliding Hinge Joint (SHJ) is a low-damage beam-column connection used in steel moment-resisting frames. It allows large beam-column rotation to occur with minimal damage, through sliding in asymmetric friction connections ... -
From Research to Practice: Case Study on Mixed Angle Screws Hold Down Connections for a 6-Storey CLT Shear Wall Building
(2024-04-09)Mass timber structures are a growing topic in the New Zealand design environment. To design mass timber buildings to the moderate or high seismic demands of much of New Zealand, strong stiff, and ductile seismic systems ... -
Geotechnical design for severe liquefiable ground improvement with SCRR technique: Waikato case study
(2024-04-09)This paper introduces an innovative earthquake geotechnical design approach for severe liquefiable ground, adopting ground improvement using the patented Subsurface Compacted Rubble Raft (SCRR) technology in a Waikato ... -
Geotechnical design of a secant piled underground pump station in liquefiable ground
(2024-04-09)The geotechnical design of underground structures with a high importance level, in a dense urban area, in liquefiable ground, and adjacent to existing structures that are sensitive to settlement is challenging because ... -
Heritage Buildings and Community Sense of Place: Towards Addressing the Challenge of Earthquake Prone Heritage Buildings
(2024-04-09)New Zealand is a nation that has a significant amount of built heritage, of which there are several internationally recognised landmarks, including the Christchurch Cathedral, the Church of the Good Shepherd, and the Chateau ... -
Highbank Power Station Redevelopment – Design Process for a Concrete Encased Turbine and Generator Plinth Replacement
(2024-04-09)Manawa Energy, a renewable energy provider in New Zealand, operates a network of 26 power schemes from the Bay of Plenty in the North to Otago in the South. The Highbank Power Station stands as one of Manawa’s highest ... -
Holistic Considerations for Low-Rise Building Design
(2024-04-09)Two low-rise residential structures, a single-storey residential structure (SSRS) and one triple-storey structure (TSS), are initially described using building information modelling (BIM) software. The structures are then ... -
Impact of base conditions on the bracing performance of LTF walls
(2024-04-09)Residential buildings in NZ are often low-rise light timber-framed (LTF) buildings where LTF walls provide the gravity and lateral load resisting systems. LTF building construction largely follows the prescriptive standard ... -
Impact of seismic demand on construction costs
(2024-04-09)The legally binding earthquake performance requirements in New Zealand's Building Act and Building Code emphasise building collapse prevention, allowing for a certain degree of damage to resist the seismic load. However, ... -
Impacts of ground motion and scaling method selection on the performance of rocking wall systems with friction connections
(2024-04-09)Dynamic time-history analysis has long been regarded as an acceptable and reliable method for seismic design of structures not covered by codal guidelines and often referred to as "alternative" design. Resilient rocking ... -
Implications for Design of Parts and Components from Updates to New Zealand Seismic Loading Standard and National Seismic Hazard Model
(2024-04-09)New Zealand engineering practitioners will see revisions to the seismic loading standards for non-structural elements (parts and components) in the draft technical specification TS1170.5. This paper considers the implications ... -
Improving Post-Earthquake Emergency Management of Heritage Buildings
(2024-04-09)The emergency response is one of the most thorny and challenging activities for the local and national authorities. It is necessary to act quickly and in an effective manner - any delay or misstep could cost lives and ... -
Improving structural performance of an existing EBF and moment frame structure using fluid viscous dampers
(2024-04-09)Improving the performance of existing buildings is a critical function for engineers and one of the most impactful ways we can improve the sustainability of buildings. By re-using and upgrading existing building stock, we ... -
Improving the Post-Earthquake Response of Hospitals: The Implementation of Priority Response Agreements
(2024-04-09)It is vital that decisions on which hospital buildings can continue to be used following damaging earthquakes are made quickly. A key component of the decision-making process is timely input from experienced engineers ... -
Indicators for quantifying post-disaster functionality: a neighbourhood scale
(2024-04-09)Natural disasters, such as earthquakes and cyclones, affect people physically and mentally. They can be destructive to the built environment, hindering infrastructure, lifelines, buildings and homes, which all support the ... -
