Investigación resistencia a compresión de la guadua angustifolia en estados de fotodegradación

Abstract

"This investigative work arises from the hypothesis ""the guadua in State ofphotodegradation without any involvement in its interior will continue fulfilling its structural function without changing the piece"", since so far there is no document which rectify and validate this information. The guaduas is a material very resistant and the most widely used in construction, but these presents an injury very common to be exposed to atmospheric agents which is the fotodegracion and from this derives a mechanism of damage: which was founded since the guaduas being exposed to ultraviolet rays begin to suffer color change by a whitish or greyish (photodegradation) , but after a while of being too long exposed to atmospheric agents UV and other rays, can get to suffer contraction of the material which leads to cracks, throughfissures becomes water which attracts the fungus and insects, and these can produce loss of material. Taking the above for the problem intends to do investigative work in which samples of all lesions of guadua (photodegradation, fissures, fungi, and insects), were to later analyze the results, conclusions and data showing the hypothesis. Research is core to logar to the guaduasthat presented lesions as fotodegracion, cracks given by contraction, fungi given by moisture and insects, unaffected in its interior, can continue presenting a useful life and is not necessary to change the piece. It is important to highlight that through research was reached provide numerical percentages of eligible efforts of the guaduas with injuries, which were made based on the standard NTC 5525 and NSR-10 chapter G wood and bamboo"
