ne of the major concerns in designing of prestressed

beams 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 induce

plastic behaviours which it is necessary to take into account by

designing of such structures, especially when they are of large

spans. In the present work, it is proposed an analytical model in

large deformation of a rigid plastic prestressed UHPFRC beam

embedded at one end and having at other end rolled support.

She is approached by a local uniform load and external moments

to supports. The proposed non-linear model can find exact

analytical solutions for the determination of the local arrows and

the associated charge by the technique of Lagrange multiplier

which allows finding the stationary points of differentiable

function of one or several variables under constraints. The

results of this work can be useful in designing and calculation

of long span prestressed structures with plastic rigid behavior.

Speaker Biography

Abelim Passoli is a PhD student in Engineering Sciences (DOCs3s4-SPI) at the

University of Abomey-Calavi, Cotonou, Benin. He is a graduate of the National

Conservatory of Arts and Crafts (Cnam) of Paris in France and of Higher National

School of Technology (ENSUT) in Dakar, Senegal. As a Construction and Planning

Engineer, he has 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.
