Takeuchi2 ABSTRACT The Universidad Nacional de Colombia -Analysis, Design and Materials - GIES- research group tested two types of panels made from Guadua angustifolia Kunth and poly vinyl acetate (PVA) as a first step in studying the behaviour of laminated guadua frames having panels of the same material under seismic load: type 1 panels had a solid cross-section and type 2 panels a sandwich cross-section. Each type of panel had three different heights and 10 replicates were tested for each type and height (60 trials in total). Each panel’s load compared to displacement curve was found; 0.34m and 0.63m type1 panels had initial elastic behaviour followed by inelastic behaviour while 0.98 m panels made of both types had an almost completely elastic behaviour until failure.
All panels became crushed at their base; however, the main failure mechanism was warping. Keywords: Guadua angustifolia, rolling, stiffness, ductility, resistance. RESUMEN Como un primer paso en el estudio del comportamiento ante cargas sísmicas de pórticos de...
