Reforzamiento estructural para forjados de madera en edificaciones patrimoniales y contemporáneas

Abstract

The development of systems for wood structural reinforcement includes a wide range of knowledge and expertise, for this reason, this thesis begins with a brief historical review about timber as a structural element. Through many different ages of mankind, timber has been a leader in the field of construction. When studying timber, it is also important to understand the features that makes it strong structural element. These features include the defects, physical and mechanical properties, and more. In order to determine the structural capabilities of the eucalyptus wood, it was important to test many different samples. Samples were taken from the beams and columns of buildings ranging from 0 to 100 years in age. These samples were then taken to a laboratory, where they were bent and compressed in different ways to test their strength and elastic behavior. However, before these samples were tested, they were divided into 3 groups. One group, which consisted of new wood, served as a reference point for the results that would follow from within the other two groups. These other groups included wood ranging from 50 to 100 years old. In each of these three groups, some wood samples were reinforced, while others were not. By compiling these results, it was found that the bearing capacity of the wood from the eucalyptus tree worsened as time went on. Therefore, a deterioration age of this type of wood was found. However, in all three groups that were tested, the samples of wood that were reinforced proved to have a higher bearing capacity than the other samples of wood. Still, some methods of reinforcement proved to be better than others. Because of this, the advantages and disadvantages of each type of reinforcement were explored, which led to the creation of a new type of reinforcement that proved to be even stronger than the existing.
