neof themajor concerns indesigning of prestressedbeams

in Ultra-High Performance Fiber- Reinforced Concrete

(UHPFRC) is improvement of their ductility fracture due to the

nature of the materials used in their manufacture. This can

induceplasticbehaviourswhich isnecessary to take intoaccount

by designing of such structures, especially when they are of

large spans. In thepresentwork, wehaveproposed an analytical

model in largedeformationof a rigidplastic prestressedUHPFRC

beam embedded at one end and having at other end rolled

support. It is approached to support a local uniform load and

externalmoment. Theproposednon-linearmodel can findexact

analytical solutions for thedeterminationof the local arrows and

the associated charge by the technique of Lagrange multiplier

which allows the finding of stationary points of differentiable

function of one or several variables under constraints. The

results of this work can be useful in design and calculation of

long span prestressed structures with plastic rigid behavior.

Speaker Biography

Abelim Passoli is a doctorate in Engineering Sciences (DOCs3s4-SPI) at the University

of Abomey-Calavi, Benin. He is a graduate of the National Conservatory of Arts and

Crafts (Cnam) of Paris in France and Higher National School of Technology (ENSUT)

in Dakar, Senegal. As a construction and planning engineer, he held several senior

positions in the public and private sector with more than 26 years of experience in the

field of transport and public works and the management of various phases of road

infrastructure, urban infrastructure, rural equipment project studies and public contracts.

As a specialist in transport economics, since 2004 he has been involved in the technical

and economic studies of infrastructure projects in Togo and in the sub-region through

the SITRASS network in the expertise and valuation of companies real estate assets.
