Seismic performance of Non-Structural elements in New Zealand – What have we learnt? by Jan Stanway

The performance of buildings in recent New Zealand earthquakes, delivered stark lessons on seismic resilience.  Most of our buildings, with a few notable exceptions, performed as our Codes intended them to with regard to safeguarding people from injury.  Many buildings only suffered minor structural damage but were unable to be reused and occupied for significant periods of time due to the damage and failure of non-structural elements. 

This talk provides an overview of the key issues impacting the design, coordination, and installation of non-structural elements and discusses how improving the seismic of performance of non-structural elements requires a holistic view of the response and function of the building.  It highlights the importance of understanding how the structural response affects the design of non-structural elements and will provide commentary on improvements to detailing, coordination and construction to improve the future seismic performance of non-structural elements.

SPEAKER BIO:
Jan Stanway is the Industry Champion for Theme 3 (Fit for Purpose Building Components which focuses on improving the seismic performance of non-structural elements in New Zealand) of the Building Innovation Partnership (BIP). Jan led the White Paper on the design, construction and seismic performance of non-structural elements in New Zealand.  The research behind the white paper included industry workshops with participates from all parts of the New Zealand construction sector.  The white paper compiled a comprehensive review of the key challenges facing the NZ construction industry, the vision for the future and the changes the industry collectively needs to embrace to ensure buildings achieve not only the Functional and Performance Requirements defined by legislation but also to meet the expectations of asset owners, tenants and our communities.  Jan is involved in the seismic design of non-structural elements in various new and existing buildings including, office buildings, hotels, libraries and hospitals.

An integrated approach to the low damage of drift sensitive non-structural elements presented by Jitendra Bhatta

Damage to the non-structural elements has been persistent during recent New Zealand earthquake events leading to considerable economic losses from repairs and downtime. Non-structural elements can be categorised as acceleration or drift sensitive. Drift sensitive non-structural elements such as partition walls and precast concrete cladding panels are required to accommodate the relative deformations between the element and the structure. Damage to drift sensitive non-structural elements is common and often attributed to detailing that does not provide adequate allowance to accommodate movement. Partition walls in particular are very often damaged and lose serviceability at a low inter-story drift unless innovatively designed to accommodate the drift demand. Collapsed cladding panels also pose a significant threat due to their weight.

This talk covers research and findings on the novel low-damage details of ‘rocking’ precast concrete cladding panels and internal partition walls tested at the University of Canterbury. It also provides advice around the importance of an integrated approach towards a buildable seismically resilient design and detailing of non-structural elements.

SPEAKER BIO:
Jitendra Bhatta is a building seismic restraint engineer at Beca and is currently involved in the seismic restraint design on numerous projects around New Zealand. Jitendra holds a PhD degree in Earthquake Engineering from the University of Canterbury. Jitendra’s PhD research focused on the development of seismically resilient drift sensitive non-structural elements, primarily the precast concrete cladding panels and internal partition walls.
