#CMT# #/CMT# The method involves removing a polymer matrix in a part (20) of an elongated stiffener (10) by pyrolysis to release stiffening fibers for rearranging the fibers after releasing of the fibers from the polymer matrix, where the polymer matrix is constituted of a thermosetting polymer. The part of the stiffener is cooled to limit propagation of heat caused by pyrolysis. The elongated stiffener is chosen from a slat shaped stiffener, cord shaped stiffener, pultruded elongated stiffener and extruded elongated stiffener. #CMT# : #/CMT# An independent claim is also included for a construction structure strengthened by a stiffener glued on a part of the structure. #CMT#USE : #/CMT# Method for strengthening a construction structure (claimed). #CMT#ADVANTAGE : #/CMT# The method allows the utilization of the elongated stiffener produced in a standard and inexpensive manner, and the rearrangement of the fibers after releasing of the fibers from the polymer matrix, so as to optimize the configuration of connection of the fibers with the part of the structure, thus considering the geometrical variations of the structure, strengthening certain zones of the structure, and distributing force between the stiffener and certain zones of the structure in a controlled manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view illustrating the arrangement of fibers released from a polymer matrix and glued to a part of a structure to be strengthened.
