Predicting yielding of gusset plates in seismic frames using finite element modelling
(New Zealand Society for Earthquake Engineering, 2020-04-22)
Gusset plates connect lateral bracing to a building by fixing two perpendicular edges into the corners of a frame. This results in a gusset plate having a non-uniform cross-sectional area and generally, each gusset plate ...
Soil-structure interactions of piled buildings on ground subject to liquefaction and lateral displacements
(New Zealand Society for Earthquake Engineering, 2020-04-22)
The lateral design of piled foundations for buildings in liquefiable ground is challenging because of potential reduced lateral support and possible lateral ground displacements. Soil-structure interaction (SSI) analysis ...
Seismic assessment and restraint of non-structural element - practical solutions and implementation challenges
(New Zealand Society for Earthquake Engineering, 2020-04-22)
Almost 10 years have passed since the 2010 - 2011 Canterbury Earthquake Sequence (CES). These major events, and more recently the 2016 Kaikoura Earthquake have confirmed the poor performance of non-structural elements ...
Impacts of innovation in performance-based building code
(New Zealand Society for Earthquake Engineering, 2020-04-22)
The purpose of this study is to assess the benefits and the unintended consequences of innovation in performance-based building code with an emphasis in New Zealand building code. Also, this paper examines how innovative ...
Annexes G and H of the Dutch Seismic Practice Directive NPR9998
(New Zealand Society for Earthquake Engineering, 2020-04-22)
The province of Groningen in the north-east of the Netherlands is currently experiencing a period of induced seismicity as the result of sustained gas extraction from an underlying gas field. These anthropogenic earthquakes ...
Unbonded post-tensioning of face loaded URM cavity walls under semi-cyclic and dynamic loading
(New Zealand Society for Earthquake Engineering, 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. ...
Estimating deformation demands on steel EBF systems
(New Zealand Society for Earthquake Engineering, 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 ...
Seismic damage avoidance design of moment resisting frames with innovative resilient connection
(New Zealand Society for Earthquake Engineering, 2020-04-22)
Moment-resisting frames are one of the efficient lateral-load resisting systems in terms of providing architectural freedom in design and imposing smaller forces on foundations. Recent major earthquakes have resulted in ...
Advanced FEA assessment of existing concrete floor diaphragms with low-ductility steel reinforcement
(New Zealand Society for Earthquake Engineering, 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 ...
Source modelling considerations for ground motion simulation validation of moderate magnitude active shallow crustal earthquakes in New Zealand
(New Zealand Society for Earthquake Engineering, 2020-04-22)
This paper summarises progress toward NZ-wide physics-based hybrid broadband ground motion simulation validation of moderate magnitude (5.0 < Mw < 7.0), active shallow crustal earthquake events through low spatial resolution ...
