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 ... -
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 ... -
Estimating deformation demands on steel EBF systems
(2020-04-22)The deformation capacity of a steel eccentrically braced frame (EBF) structure is typically governed by the chord rotation capacity of the EBF links. Codes allow these chord rotation demands to be estimated a variety of ... -
Finite element method for designing HF2V device force capacity
(2020-04-22)Supplemental energy dissipation devices are increasingly used to protect structures, limiting loads transferred to structural elements and absorbing significant response energy without sacrificial structural damage. High ... -
Influence of failure mode uncertainty on the collapse capacity of RC components
(2020-04-22)Acceptance criteria for reinforced concrete components are selected based on the assumption that the failure mode of a component is deterministic. This paper makes a case suggesting that such an assumption may be untrue ... -
Seismic response of half-scale seven-storey RC systems with torsional irregularities: blind prediction
(2020-04-22)Past earthquakes have highlighted vulnerabilities to damage or collapse of building structures due to torsional response. While methodologies to capture torsional demand due to strength and stiffness irregularities have ... -
Seismic retrofitting of RC-frames using Resilient Slip Friction Joint toggle-bracing system
(2020-04-22)Seismic retrofitting of the current non-ductile or limited ductile RC buildings is one of the challenging design topics among the scholars and engineers. The common technique for RC-frame retrofitting involves adding ... -
Self-centring bracing system: avoidance of elastic buckling for braces with one intermediate damper
(2020-04-22)Today, more attention is being given to timber material by practitioners as a structural member owing to benefits that this material can offer such as high strength to weight ratio, being environmentally friendly and ... -
The seismic performance of structural steel buildings in the 2010/2011 Christchurch Earthquake series and the 2016 Kaikoura earthquake: lessons learned, ongoing research and needs of industry
(2020-04-22)At least 20 earthquakes greater than Ms 7 have taken place in New Zealand since 1850. The recent earthquake that occurred in Kaikoura (Ms 7.8) is considered one of the largest earthquakes since 1855, but Christchurch's ... -
Unbonded post-tensioning of face loaded URM cavity walls under semi-cyclic and dynamic loading
(2020-04-22)An unbonded post-tensioning (PT) system installed into full-scale face loaded (out-of-plane) URM cavity walls using threaded rod and steel anchor plates spanning the cavity was investigated through experimental testing. ...
