This research aims to assess the effect of intemperism on physical and mechanical properties of bamboo stalks Guadua angustifolia Kunth, which came from a plantation located in La Florida, Cajamarca. The bamboo samples were subjected to intemperism for six months (June to December 2017) in the district of La Molina, province of Lima, Peru, placed at three exposure angles: 0, 45 and 90 degrees. During this period, physical properties such as moisture content and density were evaluated; additionally, color change tests were performed. At the end of the process, some mechanical properties like compression parallel to grain, bending and tension were compared before and after the exposure period. It was found that characteristics of bamboo were significantly affected by climatic conditions as: temperature, radiation and humidity at La Molina, Lima – Peru, therefore it was noticed variation in color properties, decreasing the modulus of elasticity (MOE) of compression parallel to grain and maximum resistance (RM) of tension. On the other hand, no variation was observed neither in the modulus of rupture (MOR) of bending nor the modulus of elasticity (MOE) after the intemperism period. Besides the maximum resistance (RM) of compression parallel to grain, showed no significant influence after the exposure period. Moreover, it can be inferred that middle area of the stem presented better behavior in terms of density and tension properties than basal area.
