Estudio teórico - experimental de conexiones especiales de madera tipo Bulldog, Appel y Alligator; sometida a carga axial en sentido perpendicular a la fibra

Abstract

In timber constructions, an important aspect and vulnerable at the same time, the connections between the different elements of the structure. In developed countries, the technical information is extensive, therefore is to take this information and adapted to country conditions. Initially timber classes and types of connectors to be used is defined. Continuous summary of rules to be analyzed is performed. This specimen characteristics and theoretical values of load capacity of joints are determined. We proceed to the manufacture of connectors and weapon specimens were tested. Specimens to compression perpendicular to the grain, wherein load curves vs deformation is obtained is tested. An analysis of the curves obtained is made and the experimental permissible load is defined, to thereby carry out a comparative study between theoretical and experimental values. A comparison between values obtained in the test perpendicular to the grain with which were obtained in a thesis before held in a parallel direction is performed. Finally a comparative analysis of joints with bolted connections, compared to using special connectors, emphasizing the wood type and connector used is performed.
