Fundamentals of Reinforced Concrete Seismic Design
The design of reinforced concrete structures in New Zealand is typically significantly influenced by earthquake actions. This seminar will provide a thorough overview of the fundamentals of analysis, design, and detailing required to ensure satisfactory seismic performance.
The course will deliver practitioner focused training, enabling participants to make an immediate impact in their workplace.
Key topic areas covered will be establishing seismic design loads, seismic design of reinforced concrete members, and recommendations for modelling of concrete structures. Throughout the seminar, the topics covered will be discussed in relation to relevant New Zealand Standards. Particular emphasis will be placed on explaining the background to design requirements and on advances and changes that have resulted from the 2010/2011 Christchurch and 2016 Kaikoura earthquakes.
Detailing of Precast Cladding, Flooring Systems & Stairs for Multi-Storey Buildings
Claddings, precast floor systems and stairs are key structural elements and their interaction with lateral load systems can drastically alter expected design performance. Moreover, poor design detailing and the incorrect installation of claddings, floors and stairs can drastically compromise the overall seismic performance of those systems. The Canterbury earthquake sequences imparted severe lessons and some traditional connection details did not perform as well as expected, with issues such as unexpected pounding between claddings, brittle failures of connections and fasteners, excessive out-plane movements, damage to floor supports and loss of stair seating. A proper review of existing connections and improvements are necessary to increase the overall robustness of claddings, floors and stairs.
The aim of the seminar is to provide a comprehensive overview of existing connection detailing and current design methodologies and propose improvements through worked examples.

Michael Collins Seminar Series
Shear Design and Evaluation of Concrete Structures
Professor Michael P Collins, University of Toronto
Deficiencies in the shear design of concrete structure are inherently more dangerous than deficiencies in flexural design because shear failures can occur with no prior warning and with no possibility for redistribution of internal forces. While accurate assessment of the shear capacity of a reinforced concrete structure is critically important for public safety, the traditional techniques available for this task are open to dispute. For determining flexural capacity engineers can use the simple, accurate, general and internationally accepted “plane sections theory”. However, for finding shear strength engineers typically rely on restricted empirical equations whose applicability and accuracy are sometimes very questionable. In this presentation research aimed at understanding the basic mechanisms of shear transfer is summarised and simple, rational and general shear design and evaluation procedures are introduced.

Seismic Assessment of Existing Bridges seminar
The identification of appropriate assessment methodologies for existing bridges has always been an important aspect of repair/ retrofit and upgrading of New Zealand’s concrete bridge stock. The need for accurate assessment tools may be instigated by a need to increase applied loadings, maintenance requirements, restoration or replacement of existing bridges – or as the result of an actual seismic event. The need to assess post-earthquake residual capacity through accurate procedures for a wide variety of road and state highway bridges damaged by the recent Christchurch earthquakes has never been more in demand.
This half-day seminar has been specifically designed to present best practice methods for carrying out this work in typical New Zealand applications. It shares the experiences of key people involved in the immediate response and reconnaissance of Canterbury bridges following the earthquakes and points out both the weaknesses and merits of existing procedures. The seminar will also demonstrate enhanced methods for assessing seismic capacity of existing bridges and also raises, for discussion, unexpected correlations such as post-earthquake durability performance.
The seminar will also assist you with the following:
• Immediate response and related integrated rational tools from Canterbury earthquakes response
• Learn assessment procedures verified through simplified numerical analyses
• Effectiveness of seismic retrofit through linkages in Canterbury earthquakes and design procedures
• Use of non-linear analyses for assessing existing bridges: Dynamic or quasi-static analysis?
• Methods for assessing bridge performance: displacement based or forced based?
• Understanding the impact of post-earthquake cracks on durability of bridges.
• Measuring the effectiveness of seismic screening procedure through Canterbury bridge stocks; can the procedure be used for other important urban centres?

Materials, Standards & Practice for Sustainable Concrete Structures
In responding to the challenges presented by climate change and limited natural resources, specifiers, asset owners and regulators are developing new approaches to improve the sustainability of the built environment. In addition to the economic impacts and social needs that have traditionally driven design and construction of buildings and infrastructure, new design procedures and tools now consider the long-term environmental impacts embodied in individual structures, including the use of energy and natural resources, creation of emissions and other wastes, transportation, ecological impacts associated with land use, and impacts on users of the structure. Thus 'sustainable design' is a multi-disciplinary process encompassing whole-of-life environmental, economic and social impacts to meet both human and environmental needs.
This seminar will describe principles and case studies relating to sustainable concrete design in Australia and New Zealand, with participants learning how to meet their clients' and stakeholders' needs for sustainable concrete structures.

Accelerated Bridge Construction in Seismic Areas: Design Detail of Bridge Piers
Accelerated Bridge Construction (ABC) is gaining popularity because it offers a number of advantages over conventional methods of construction. Prefabrication of bridge components for rapid onsite assembly is a highly effective ABC approach and has been used for a number of decades in the construction of bridge superstructures. Prefabricated bridge substructures are becoming popular especially in traffic dense areas but are mainly used in regions of low seismicity in part due to a lack of reliable ductile connections. However, in the last decade, extensive research funded by several Departments of Transportation (DoTs) in the US and Japan led to further implementation into real bridges of cast-in-place emulative connection detailing for high seismic regions.
The aim of the seminar is to provide a comprehensive overview of ABC substructures connection detailing and current design methodologies through worked examples and highlight constructability aspects through case studies.
