A displacement-based design method of low-damage dual systems with hysteretic and nonlinear viscous energy dissipation
(2023-04-19)In 2019, a large shaking-table test was performed for a full-scale two-storey low-damage concrete wall building. The test building comprises unbonded post-tensioning (UPT) rocking walls and perimeter frames in both directions. ... -
Achieving earthquake-safe buildings – an educational initiative for developing nations
(2023-04-19)Building departments in developing nations have a poor track record of achieving earthquake-safe new buildings. Many buildings, within their jurisdictions are not expected to perform well in medium- to high-intensity ... -
Risk thresholds in the built environment
(2023-04-19)Engineering and building design inherently deal with risk. But risk is rarely—if ever—explicitly considered. Most building design in Aotearoa New Zealand (i.e., to B1/VM1 NZS1170) targets an annual individual fatality risk ... -
Societal Expectations for Functional Recovery of Primary and Secondary School Buildings
(2023-04-19)In the ongoing investigation of functional recovery requirements, the spectrum of functional requirements for different facility types is necessary to ensure buildings are designed, constructed, and maintained to meet ... -
Public expectations of damage and disruption to existing multi-storey buildings in earthquakes
(2023-04-19)The seismic performance of both structural and non-structural building components have the potential to affect the lives of building occupants, with poor performance likely to cause undue disruptions to the lives of building ... -
Site-specific seismic hazard evaluation of critical bridge infrastructure in Cebu, Philippines
(2023-04-19)Long-span, inter-island bridges in active tectonic regions are exposed considerably to elevated seismic risks. Evaluation of the seismic hazard is a primary step to assess this risk. Baseline information can be obtained ... -
Seismic hazard analysis for a bridge across Marikina River with consideration of near-fault effects
(2023-04-19)The Valley Fault System in Metro Manila, Philippines is widely considered to be an impending threat in releasing a large-scale earthquake. Such earthquake is forecasted to impose severe casualties and economic losses to ... -
Evaluation of prioritization schemes for bridge stock assessment
(2023-04-19)The important role of bridges in transportation network resiliency has made the management of the existing bridge stock an essential task. In order to implement and prioritise the activities to secure the proper performance ... -
Elongating plastic hinge element for nonlinear analysis of RC structures using OPENSEES
(2023-04-19)During inelastic cyclic loading, the length of plastic hinges in reinforced concrete (RC) members increases irreversibly which significantly affects the seismic performance of RC structures. It is hence necessary for ... -
Cyclic behavior of older concrete columns reinforced with high-performance fiber reinforced cementitious composites
(2023-04-19)Many older existing reinforced concrete (RC) buildings were designed without considering seismic loads. In such buildings, columns may be the most vulnerable element because they generally have insufficient reinforcement ... -
Timber-based seismic retrofit of a 5-storey RC structure built in 1955
(2023-04-19)The paper presents a study on the seismic behaviour of a 1955 masonry-infilled reinforced concrete (RC) building subjected to two alternative timber-based interventions to reduce its seismic vulnerability. The first ... -
Area Ratio or Volumetric Ratio: Which is better for quantifying the confinement of concrete?
(2023-04-19)Confinement of concrete helps in improving ultimate strain of concrete. This increase depends on amount of transverse reinforcement in the vertical member. While the need for 1350 hooks in transverse reinforcement is ... -
Avoiding moat wall pounding of base-isolated buildings using D3 viscous dampers
(2023-04-19)Base-isolated buildings are typically important facilities expected to remain functional after a major earthquake. Seismically isolated buildings can experience large displacements at the isolation level during strong ... -
Effect of serviceability and over-strength mechanism on seismic response of low damage structures
(2023-04-19)Low-damage structural systems are designed in a way the earthquake damage is controlled and localised in pre-designated locations and components (e.g. fuses). These components are normally replaced, repaired or designed ... -
Earthquake strengthening clay brick masonry parapets – proof-tested solutions
(2023-04-19)Unrestrained unreinforced clay brick masonry (URM) parapets are found atop of a large number of vintage URM buildings. Parapets are typically cantilevered wall structural elements that form decorative and ornamental features ... -
A Sensitivity Study of the Design Parameters Affecting the Global Stability of Buckling-Restrained Braced Frames
(2023-04-19)Recent research has focused on the ability of buckling-restrained braces and their connecting elements to act together as a series of resisting elements to resist mechanism formation. This potential failure mode is known ... -
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 ... -
Chevron Buckling Restrained Brace Frame Seismic Behaviour Considering Out-of-Plane Effects
(2023-04-19)This project evaluates the behaviour of buckling restrained braces (BRBs) in a chevron configuration considering IP and OOP frame deformations using software capable of second-order inelastic frame analysis. Initially a ... -
Response of Retrofitted 3D RC Frames under Dynamic Loading Conditions
(2023-04-19)In this study, the response of 3D double story reinforced concrete (RC) frames retrofitted through a diagonal friction damper under dynamic loading conditions, was evaluated using shaking table tests. A friction damper ... -
Seismic strengthening of RC walls using FRP to prevent axial failure
(2023-04-19)Reinforced concrete (RC) walls with insufficient compressive strain capacity at the boundary region are vulnerable to premature axial failure, limiting the drift capacity. A solution to strengthen these deficient RC walls ...
