Abstract: This article presents the experimental tests results of frames made with glued laminated pressed bamboo guadua under lateral load. The tested frames had two floors with 1.40m of height each one and 2.80m of total height; the width of the frames was 2.10m. Beams and columns had square box cross-section of 0.10m side and 0.015m of wall. Three frames had bracing type K and other threes had panels. The adhesive used for the manufacture of beams, columns and braces was Urea Melamine Formaldehyde and for the elaboration of panels was Polyvinyl Acetate. The frames of glued laminated pressed bamboo guadua had elastoplastic behavior with great ductility.

Abstract: The earthquake on 1999 in Armenia city (Colombia) showed the good seismic performance of structures using bamboo guadua as main material but also the mistakes caused by improper techniques of construction and the lack of parameters design for this type of structures. This work presents the experimental methodology used for the determination of allowable stresses for the design of bamboo guadua structures, used in the project "Validation of Guadua Angustifolia as a structural material for design, by the allowable stresses methodology" financed by the Ministry of Agriculture and Rural development of Colombia (Ministerio de Agricultura y Desarrollo Rural de Colombia) and developed by National University of Colombia (Universidad Nacional de Colombia) since the year 2008 when there were no allowable stress design standards for this structures in Colombia. For the determination of the allowable stresses were carried out tests of samples in compression, tension, and shear parallel to the fiber, compression perpendicular of the fiber and bending beams with bamboo guadua from three different areas of Colombia. It was found also the flexural elastic modulus for the material.
