Lapped scarf joints for repairs of historical structures

Abstract

ii This method is intended for the administrators of historical buildings, designers and workers, and organizations performing repairs of timber members and structures of historical buildings in order to ensure high quality of the preparation and execution of works for the preservation, long-term sustainability, high reliability, and safety of wooden structures. Opponents AbstractThis paper presents a description of the repair of timber structures using a prosthesis scarf joint designed for the replacement of damaged parts of beams. This new scarf joint makes use of the strutting effect of inclined contact faces where the forces are transmitted through wooden coupling elements -wooden dowels or keys. The scarf can be modified in four variants according to the relevant stress and is suitable for historically valuable timber structures. It meets both functional and aesthetic requirements. The designer -structural engineer will learn in the methods the load bearing capacity or stiffness of the beam with the designed joint, its recommended dimensions and detailed geometry. The contractor will appreciate the description of the execution and maintenance of the joint.
