Experimental Studies of Operation of Timber Compressed-Bent Elements of Built-Up Section with Ties in the Form of “CF-Casings”

Pliable connections of wood composite compressed-bent elements with the use of unidirectional carbon-fiber (CF) tapes on the epoxy matrix are considered. The goal is set, tasks are developed for the implementation of the experimental study of wood composite compressed-bent elements. The method of manufacturing and the process of hardening of wooden samples are described. The technique of field studies was developed: the scheme of loading of a compressed-bent wooden rod was proposed. The results of experimental studies of wooden composite compressed-bent elements of full-scale dimensions are presented. A comparison of the results of experimental study and computer analysis of the wooden composite compressed-bent element with the pliable tiess in the form of unidirectional carbon fiber clips on the epoxy matrix is carried out. The ductility of the connection made of unidirectional carbon-fiber tapes with the epoxy matrix for wood composite compressed-bent elements is estimated.
