SUMMARY:Structures Seminars – Alphose Zingoni (Cape Town): Symmetry\, Gro
 up Theory and Applications to Structural Mechanics
DESCRIPTION:Abstract:\nThe presentation will outline some of the work carri
 ed out at the University of Cape Town on symmetry in structural mechanics\
 , and explain how group theory has been applied to simplify computations\,
  study the physical properties of structural systems\, and explore new pos
 sibilities. These studies have included (i) the static analysis of space f
 rames\, (ii) the vibration behaviour of grids\, cable nets\, plates and sh
 ells\, (iii) the buckling of space trusses\, rigid frames\, plates and she
 lls\, (iv) the development of group-theoretic numerical formulations\, and
  (v) the innovative use of group theory in creating novel configurations o
 f space structures. After outlining basic concepts of symmetry and group t
 heory\, the talk will illustrate the group-theoretic approach by reference
  to the vibration of a double-layer cable net. Through a numerical example
 \, the talk will highlight the usefulness of group theory in predicting th
 e behaviour of the structure prior to any detailed calculations\, and in s
 implifying the computation of key structural properties.\n\nBio:\nProf Alp
 hose Zingoni is Professor of Structural Engineering and Mechanics in the D
 epartment of Civil Engineering at the University of Cape Town. He obtained
  his PhD from Imperial College London in 1992\, and spent a further 2 year
 s there as a Research Fellow of the Royal Commission for the Exhibition of
  1851\, before joining the University of Zimbabwe. After serving a 3-year 
 term there as Dean of Engineering\, he moved to the University of Cape Tow
 n in 1999\, later serving a 5-year term as Head of Department of Civil Eng
 ineering. His research has focused on analytical methods for shell structu
 res\, innovative use of shells\, studies of symmetry in structural mechani
 cs and development of group-theoretic formulations. He is the founder of t
 he SEMC International Conference\, held in Cape Town every 3 years since 2
 001\, and currently serves on the editorial boards of four Elsevier journa
 ls. He is a Fellow of the UK Institution of Structural Engineers\, a Fello
 w of the South African Academy of Engineering\, and a Fellow of the Univer
 sity of Cape Town.\nOpen to all. Attendees external to Imperial need to re
 gister. \nTime: 12:00 noon
