PREFACE

M

2 D , 2006

is the fifrh intemati onal gathering af scientists and engineers interested in

the fields ofengineering mechanics, design and materiaIs engineering planned for July 24-26,

2006

in the bcautiful city

Df

Porto, Portugal. This is a well-established meeting with fo llowers

from some 35 nations.

The first conference af this series was held in Toronto in 1996 and attracted over ] 50

delegates. The second was organized

by

Professors .1.8. Hull and R. Gentle in Nottingham in

1998. The third was 'organized by Professor S.A. Meguid in Orlando in 2000. The fourlh \Vas

organized

by

Dr. T. Mori and Profes sor H. Fujii in Nagoya, Japan in June 2002. These

meetings resu lted

[Tom

the belief that af those disciplines associated with advanced product

design and manufacture, engineering mechanics and materiaIs engineering have made the

1110st signiticant advance in recent years. Important and dramatic improvements in component

design cnn be made by the use of the Iatest advances in mechanics and materiais. Indeed, as a

result of the activities in these three important fields: Mecl1anics, Materiais and Design, lhe

International Joumal of Mechanics and MateriaIs in Design was established in 2004. With

Professor lF.

Silva Gomes being an impanant member af the Editorial Board and Professor

Shaker A. ivleguid being its Editor-in-Chief.

lt

is with this in mind that this

Fiftlr I/ltel'/1atio/1111

is organized. The purpose is to bring together scientists and engineers from the

mechanics and materiais commullities to present their latest results and discuss new advances

over a broad range oftopics dealing with analytical, numerical and experimental techniques in

mechanics and advi.1llces in materiaIs' tcchnology as well as case studies. VI/e have done our

best to provi de the delegares with an cnvironment conducive to exchange of knowledge,

networking and making new friends.

\Ve take this to thank our colleagues \V110 contributed considerably to the event by organizing

topical symposia and by hei ping

tiS

to launch this important meeting. We are truly grateful for

their efforts. We aIs o wish our overseas friends to have a great time in Portugal. We wish you

ali a happy and successful slay in Porto.

Safe design is a design process that eliminates hazord s, or mmltTIlzes potential risks,

by

invo!ving decision makers and considering the life cycle af structures and materiais. Safe

design approach wil1 genemte a \vell-informed design option that should eliminate these

potenHa! problems to those \Vho makes lhe product and to those who use it.

Structu ra\ and materia l safely in design will

cave r the design aspects af safe slructures, using

steel, concrete, timber and composite material elemems. Accidental conditions should be

carefully understood and considered according to the safety stondards and regulations.

Advances in stalldards and regulations should permanentJy ensure safety with the best

praclices and methods. Advanced analysis methods shou ld be pennanently improved and used

lo prevent such potential risk in slructures Jlld materiaIs. Designers shou ld guarantee

stl1.lclural integrity and prevent structura l damage.

The papcrs presented in this Sympos ium wi lJ address ditTerenl aspecLS in structural and

material safety in designo

SYNOPSIS

Partial1y encased beams are composed struchlral elements widely used for industrial buildings

with increasing slgnificance. Composite beams may be designed for service load conditiol1s

without the col!aborative cantributian af slabs. Instability problems may aceur because

concrete may not have tbe age to resist and also beeause the concrete may slip oveI' steel,

crack or crush. Lateral torsional buckling is an instability limit state that may oceur in these

situations.

This papel' presents a material and geometric l10n linear tinite element model for the desigll af

lateral torsianal buekling resistance of partially eneased steel beam without encasernent

reinforcements. The steel part

ar

the eamposed sectian will be modelled

by

shell, eoncrete by

three. dimensional solids and the bond contaet with nOl1 linear spring finite elements. Failure

af conerete will also be predicted when the beam is subjeeted to a constant bending moment.

[NTRODUCTlON

Slabs may not transmit the stabilizing effect to prevent lateral tarsianal buckling

(LTB).

Also,

eonc.reling the steel beam within 7 ar 8 days provides less torsional stiffness than after 28

days (Boissonade et ai, 2004). This instability phenomenon is respansible for a simultaneous

lateral displacement and cross-section rotation. This means that bending around the minor

axis and torsion ahout the longitudinal axis of the element are involved.

This work intends to be the preliminary phase af a full-scale test program in (ire conditions,

complemented with numerical research and intends to deal \Vith the interaction between

concrete 3nd steel, tinding failure af concrete that may ocem during instability. Non linear

Th e real behaviour

The ultimate LTB moment resistance corresponds to the maximum load bearing capacity,
