Effective and economic combination of seismic isolation and vibration insulation within one innovative device
(2024-04-09)Seismic isolation is a well-known approach to reduce the risk of casualties as well as structural and content damage due to earthquakes. Vibration insulation on the other hand is increasingly a requirement in urban areas ... -
Enhancing Structural Resilience: Three-Dimensional Seismic Isolation (3DSI) in Practice
(2024-04-09)This research introduces a novel three-dimensional seismic isolator designed to evaluate the coupled horizontal-vertical responses of a five-story building. A comprehensive structural analysis using the OpenSees software ... -
Estimation of electricity supply restoration time with interdependencies under cascading hazard risk approach
(2024-04-09)The electricity infrastructure network functions as a system with several components interconnected and distributed over a region. When subjected to earthquake and its related cascading hazards, the vulnerable components ... -
Evaluating and Communicating Seismic Risk for Low Rating Buildings
(2024-04-09)There are many challenges for owners and occupiers of buildings where seismic assessments produce ratings of less than 34%NBS, including addressing questions about whether they should continue to occupy the building. MBIE’s ... -
Evaluating the benefits of rocking shallow foundations
(2024-04-09)Rocking foundations can offer significant benefits both in terms of seismic performance and reduced embodied carbon. This paper applies a displacement-based design procedure to achieve a rocking foundation for a multi-storey ... -
Evaluating the Effect of Initial Gravity Forces in Buckling-Restrained Brace Frame Braces
(2024-04-09)It is common practice to design buckling-restrained braces (BRBs) for seismic forces only, and to neglect any initial gravity that occurs in them. This practice assumes that these gravity loads simply “shed” upon first ... -
Experimental and Analytical Study of Fillet Welds for Seismic Actions
(2024-04-09)New Zealand steel standards NZS3404 uses a simplified method to predict the weld design capacity and to size the weld. According to the industry feedback on the design and manufacturing of the seismic welded connections, ... -
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 ...
