Cyclic tests of an innovative seismic bracing member - multiple U-shaped flexural plates dissipater
(New Zealand Society for Earthquake Engineering, 2020-04-22)
Following Canterbury earthquake sequence, there has been an increasing interest in development of low-damage structural design using supplemental damping such as the use of metallic dissipaters. In this research, an ...
Simplified design procedures for shear piles subject to liquefaction induced lateral spread with evacuation
(New Zealand Society for Earthquake Engineering, 2020-04-22)
The lateral load transfer between a pile and laterally spreading ground during an earthquake is a complex soil-structure interaction problem given the significant nonlinearity of the stress-strain behaviour of soils during ...
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 ...
