Investigación de patología en guadua del parque jardín botánico Jose Celestino Mutis

Abstract

This investigative and analytical work on the guadua`s bridge, whose focus is photodegradation. Initially, it arises from the hypothesis about the prevention design of the guadua`s bridge on the botanical garden José Celestino Mutis, located in the city of Bogotá, Colombia. It is proposed to increase the eaves and demonstrate the feasibility and probability of increasing the shade to avoid the photodegradation accretion of the Angustifolia Kunth`s Guadua from the direct impact of the sun's ultraviolet rays. This corresponds to 25%, adding the indirect impact of the lake that surrounds it 15%. Guadua´s use as a sustainable structural material has not had major investigations aimed at the prevention of photodegradation, in the research it is determined that this pathology does not generate a mechanically direct impact, but this generates secondary injuries such as cracks, bacteria, and / or pests. This causes alterations in the interior parts of guadua losing the endurance ability. Considering that the bridge to be investigated is located around a lake being more attractive for this type of biotic agents. Therefore, a design analysis is carried out, collecting maintenance information, photographs with details of the pathology, in order to show their progress; data collection for the planimetry´s creation, location, solar radiation data in Bogotà, Colombia, shadow simulation in the skepchut program and a bibliographic review, to arrive at the proposal´s viability, comparing if the increase of the eave with the initial design manages to shade the critical points of the bridge, to reach the hypothesis and to conclude recommendations for future researchers.
