Estudio de caso del domo kiddies análisis de protección por diseño contra las lesiones atmosféricas

Abstract

Guadua is a resistant material and used in construction. But it shows common damages for being exposed to atmospheric agents, such as photodegradation; from this is derived secondary damages; which arises when the guaduas are exposed to the ultraviolet rays, it begins with a color change such as whitish or grayish, but when they are for a long time exposed to the ultraviolet rays and other atmospheric agents, they could suffer a material contraction which can cause fissures, through the fissures the water passes which attracts insects and fungus, as a result, it can produce loss of material. With the purpose of analyzing the main causes which become deteriorated the guadua, eucalyptus and steel, it made a case study analyzing the durability of materials in a dome about six year of built in Mundo Aventura Park from Bogota DC, Colombia. The case study methodology was based on compilation of information, classification of deterioration, and a vulnerability rating to the atmospheric factors. It has been established on a scale about four levels for the protection evaluation about the dome design evidenced its reach and benefit in materials. It has been made many trials of climatological laboratory in the Gran Colombia University with differing periods and times, establishing the percentage of structure protection against the atmospheric factors. The case study was the base for demonstrating that the guaduas which shows a bad protection for design, they acquire damages such as photodegradation, fungus as a result of humidity and insects, this caused because of constantly maintaining, piece replacements for restoration. Different if it has a good protection for design from the beginning, on the basis of the NSR-10 norm, Woods and Guaduas chapter.
