Resistance to bending of solid beams and laminated beams for two types of woods, in the city of Cajamarca

Abstract

This research evaluated the flexural strength of solid beams and laminated beams for two types of wood, in the city of Cajamarca, due to the need to know the capacity of these two types of wood: Eucalyptus and Pine; since both types of wood are easily available in the city of Cajamarca, as well as being inexpensive in the local market. The tests were carried out in the laboratories of the Faculty of Engineering of the Universidad Privada del Norte, Cajamarca headquarters. Protocols were used for the execution of tests, whose results were processed in Excel spreadsheets, then they were analyzed and interpreted for each type of specimen: solid beams and laminated beams (wooden sheets joined together, with synthetic glue based on polyacetate vinyl). To obtain the flexural strength of the wooden beams, a maximum load was applied on the universal testing machine, considering the dimensions and the distance of the support. In the execution of the investigation, we first proceeded with the recognition of the material, its cuts and the production of the solid and laminated wooden beams, considering the dimensions of the wooden beams, based on the tests, to determine up to how much load can stand. Subsequently, the information obtained was processed and it was determined that the performance of the Eucalyptus solid beams had better performance than the Eucalyptus laminated beams, in the case of the Pine solid beams and the Pine laminated beams, these had similar behavior.
