Engthening of existing steel beams using CFRP

Abstract EN

The strengthening of the steel beams is the only way to solve the problem of damage
due to several factors, The means of support is always associated with the manner and
strengthening in terms of the risk and the operational status, The mineral origin of the
consolidation is simple and easy in terms of implementation method whenever he has
the acceptance and desire to follow this method for that In this study we will
strengthen the steel beams in the operating mode and by strengthening them with
sheets of CFRP in many shape to reach the best of these methods.

The aim of this research is to study the strengthening of steel beams in sheets of
CFRP, by means of three shapes and their comparison using many sections and many
lengths for modeling purposes.

In order to analyze the result, a finite element analysis
software ANSYS version 15.0 and software SAP version 16.0 is used.

Moreover, a comparison is conducted between results of the ANSYS and SAP
program by conducting laboratory tests for three samples similar in properties and
dimensions and different in the shape of the CFRP.

A comparison will be made
between the load and the deflection of all tested elements, whether the laboratory test
or the representation of the section in the ANSYS or SAP program.
