Design & Construction of High Rise Concrete Structures

REGISTRATION

 

Overview









 
 
Developments in the design and construction of high rise (tall) concrete buildings are rapidly evolving around the world. Traditionally, tall buildings have been designed and built for commercial offices in large urban areas. Today, with changes in social and physical needs, these high rise structures are now being constructed in all regions for residential apartments, hotels, shopping centres, and multi-purpose uses.
 
In Australia, concrete has laid the cornerstone for tall building construction leading to a rich history of success. Australia Tower, one of this country’s first concrete high rise buildings, turns 50 this year and was a landmark achievement when constructed in 1967. It remained Australia’s tallest building (170 metres high) until 1976. Since then many more tall concrete structures have been designed and built in Australia for a variety of reasons, 
 
Our seminar on Design and Construction of High Rise Concrete Structures brings together leading local experts in the crucial element of wind engineering requirements, as well as more specific concrete related areas involving materials specification and construction practices.
 
Together they will seek to show us where this country has come with respect to the way concrete is used for high rise design and construction, and provide delegates with an insight to new and developing trends, along with in-depth understanding in their areas of expertise.
 


Presenters
 

Bill Melbourne - Bill has over 50 years’ experience as a researcher and engineering consultant in wind engineering and has an active research interest in the areas of wind loading and response of structures to wind action, model of wind flow over complex terrain, turbulent flows and their interaction with bluff bodies, and dispersion of atmospheric pollutants. Bill has authored over 200 peer-reviewed journal papers, numerous conference papers, and lecture notes that are used by wind engineers around the world. Bill's contribution to wind engineering and fluid mechanics extends to service on many national and international committees including Standards Australia and the Council on Tall Buildings and Urban Habitat. 

 


Dr James Aldred - James has over 30 years’ experience in the concrete industry in Australia, Asia, the Middle East, the United Kingdom and Canada. His background includes Technical Director of an international building materials supplier, Manager of the High Performance Concrete Research Group at the National University of Singapore, Technical Manager of Taywood Engineering, and Adjunct Associate Professor at the School of Civil & Environmental Engineering, UNSW. Dr Aldred is a fellow of Engineers Australia, the American Concrete Institute, and the Institute of Concrete Technology. In 2009, James’s work on the Burj Khalifa received the CIA Award of Excellence in the Concrete Technology Category.
 

 

Topics and Themes

 

Introduction to wind engineering and wind effects on concrete structures (Bill Melbourne)
 
  • Specific description of the response of tall buildings to wind action
  • Mechanisms causing ULS wind loads and acceleration response (motion sickness)
  • Examples of wind tunnel model studies to determine the above design parameters and aerodynamic shaping to reduce wind loads.
  • The mechanics of facade pressures, associated design pressures and wind tunnel model studies
  • Effects of vented facades
  • Full scale measurements on tall buildings, facade features sunshades and fins
  • Design of dampers to reduce the response of tall buildings, masts and other structures
 
Concrete Materials Specification (James Aldred)
 
  • Compressive strength and modulus requirements for high rise
  • Appropriate temperature limits and crack limits for concrete
  • Rheology and pumpability considerations
  • Concrete mix selection
  • Creep and shrinkage issues related to high rise construction
 
Construction Practices for High Rise (James Aldred)
  • Planning and controlling large volume pours
  • Practical temperature control for massive elements
  • Ongoing quality control
  • The use of self-consolidating concrete
  • Planning and controlling long distance pumping
 

Who Should Attend?


This is a wonderful opportunity to bring contemporary thinking and practices on the design and construction of tall concrete buildings to all structural designers, engineers, and consultants, as well as civil engineering contractors, commercial design and material consultants, government engineering bodies, and concrete material suppliers.
