"RESTRUCTMAD 20-21" RESTRUCTMAD-INVESTIGATION AND DEVELOPMENT OF INNOVATIVE SOLUTIONS FOR REPAIR AND REINFORCEMENT FOR WOOD STRUCTURES DESCRIPTION The purpose of this project is to research and develop innovative solutions for the repair and reinforcement of wooden structures, with substantial improvements over existing ones: greater resistance and bearing capacity, lower environmental impact, lower cost and use of materials, shorter execution time, direct application on site, etc. OBJECTIVES The general objective of the project is to research and develop innovative solutions for the repair and reinforcement of wooden structures, with substantial improvements compared to existing ones: greater resistance and bearing capacity, lower environmental impact, lower cost and use of materials, shorter installation time. execution, direct application on site, etc. The wooden structures to which the project refers correspond to buildings, bridges, walkways, agricultural warehouses, industrial warehouses, etc. The innovative solutions that will be developed will be general enough to apply both to old and heritage buildings as well as to modern and current buildings, since there are many buildings with wooden structures or derived materials that present structural problems due to lack of knowledge of the material, due to erroneous design, deficiencies in the structural calculation or incorrect execution, or by a combination of all these factors. Likewise, there are many old and modern buildings that change their use (and as a consequence of structural and regulatory requirements), and require repair and reinforcement solutions that allow the existing structure to be adapted to new requirements, without incurring costly renovations or problems derived from the use of other materials for which the structure was not designed or calculated. Project Number: 22000046 Grant Agreement: IMDEEA / 2020/18 Duration: From 01/07/2020 to 30/09/2021 Coordinated in AIDIMME by: ABIÁN PÉREZ, MIGUEL ANGEL R&D Line: BIOMATERIALS EXPLANATORY VIDEO RESULTS OBTAINED Year 2021: A complete analysis of the mechanical properties of wood in old and modern structures has been carried out. A detailed analysis of the most frequent situations in structures that require reinforcement or repair has been carried out. A study of the current solutions to repair and reinforce wooden structures has been carried out, from which some technical sheets of the solutions have been generated. Innovative reinforcement and repair solutions have been developed, with substantial advantages over existing ones in three aspects: sustainability, competitiveness and reliability. The three solutions developed have been through rigid reinforcing elements embedded in resins, through strips of fiber-reinforced polymers (FRP) applied in an overlapping and also embedded manner, and through wooden prostheses. With the solutions developed, elements with low resistance, degraded or with breaks or beginnings of breakage have been repaired/reinforced; and then the mechanical characterization was carried out, according to the CTE, of the repaired/reinforced elements. For repair using rigid reinforcing elements embedded in resins, of the 11 innovative mixtures developed, the sand + sawdust and sand + cork formwork mixtures are the ones that best meet the following two requirements, which are essential for a repair solution for structural wood: a) Good adhesion and solid union of the mixture to normal wood, without degradation; b) Total flexural strength of the repaired element very similar to or greater than that of the “healthy” element. Both mixtures do not increase the bending resistance of the repaired element, but they do provide a resistance very similar to that of “healthy” wood of medium quality. In addition, they use renewable and recyclable raw materials (cork and sawdust). The FRP reinforcement solution is very effective and fully compatible with wood. It significantly increases the flexural strength and elastic modulus of the reinforced joists. In the case of the FRP inserted in the lower face of the joist, the MOR increases by 19,65%, and the MOE, by 20,82%. In the case of the FRP adhered to the lower face of the joist, the MOR increases by 31,30%, and the MOE, by 29,54%. This solution also has the advantage that it is easy to apply both in the laboratory and on site. With the repair solution using wooden prostheses, in none of the cases tested is it possible to exceed 14 N/mm2 on average (which would correspond to a resistance class of C14, which is the minimum resistance class of the CTE), which is why considers that the chemical block used in this solution is not suitable for rehabilitation, or that the type of cut must be more complex to allow a larger gluing surface. Between 60 and 70% of strength is lost compared to the flexural strength of the original joists. In the future it will be necessary to investigate more chemical blocks or develop one specific for wooden prostheses, as well as test them with more complicated cuts than the vertical or diagonal (for example, Jupiter ray). Finally, an application guide for the developed solutions has been prepared. Year 2021: Deliverable 3.3.
