WHY YOU & YOUR EMPLOYEES SHOULD ATTEND THIS SEMINAR

Prestressing of concrete, through pre-tensioning or post-tensioning techniques, emphasises the advantages of concrete to enable the design and construction of elements with longer spans, slimmer profiles and enhanced serviceability performance.

The use of prestressed concrete in New Zealand grew throughout the second half of the 20th Century, and is one of the most common construction practices for building floors and lateral load systems, bridges, and civil infrastructure projects.

The design principles and construction methods for prestressed concrete elements differ substantially from reinforced concrete. The seminar will introduce the key learnings underpinning prestressed concrete, the key differences and similarities between reinforced concrete and prestressed concrete, and how these concepts are applied in design and construction.

THIS SEMINAR WILL COVER

• Materials & prestressing technology
• Fundamentals of pre-tensioned and post-tensioned concrete members including load balancing concepts
• Design and checks for SLS including stresses, deformation at different stages and short/long term losses
• Design and checks for ULS flexure design
• Design and checks for ULS shear design
• Worked example

SPEAKERS PROFILES

Alessandro Palermo
Dr. Alessandro Palermo is a professor of structural engineering at the University of Canterbury and Director of the Research Postgraduate Students at the Department of Civil and Natural Resources Engineering. He is actively involved in research related to seismic response of low damage post-tensioned concrete bridges and buildings and the use of smart sustainable materials and construction technologies. His early career research covered temperature, creep and shrinkage interaction in post-tensioned concrete bridges. Alessandro is the recipient of several national/international research awards, published over 350 conference/journal papers and is co-inventor of 3 patents. Alessandro currently teaches prestressed concrete in the undergraduate programme and bridge engineering at both undergraduate/postgraduate level. He loves teaching and his enthusiasm and dedication to teaching has meant a number of awards, including five University Student Union (UCSA) Awards and a University of Canterbury teaching award. Alessandro has recently been awarded Engineering NZ and NZSEE fellowships. He is currently the Vice-President of the Concrete NZ Learned Society and New Zealand fib Head delegate.

Moustafa Al-Ani
Dr. Moustafa Al-Ani is a structural engineer at Compusoft Engineering with interests in bridge and civil structures, concrete structures and material, seismic analysis and design, and soil-structure interaction. Moustafa has experience in the analysis, design and management of bridge and civil infrastructure projects in New Zealand and overseas, as well as experience in the seismic analysis of multi-storey building structures. Moustafa’s research interests include concrete structures, the seismic performance of bridge structures, and seismic isolation of bridges. He maintains an interest and participation in associated research. Moustafa is a Chartered Professional Engineer and an active member of the engineering community, currently serving as a member of the Concrete NZ Learned Society Council and convener of the SESOC Auckland Bridge Group.
