Abstract

This paper describes the behaviour under lateral load and propose a model to assess the lateral stiffness of panels in scale 1:1 assembled with masonry units made of recycled paper, cardboard buckets for eggs storage, and Yucca starch. Three panels of 1.56m in height, 0.47 in width, and 0,090m in thickness were assembled using the recycled paper masonry units, longitudinal reinforcement and metallic confinement elements. Results show that the panel behaviour under lateral load is ductile given that the panel can undergo drifts up to 15% with low damage on the masonry units or on the confinement elements. A model for predicting the lateral stiffness of the panel was proposed based on the shear stiffness of the set of the masonry units. Results also show that the stiffness model over estimates the panel lateral displacements up to 13%. The panels are proposed as nonstructural partitions for buildings because they are light, easy and fast assembly, dismountable, they can be protected against humidity and fire; and more importantly, after a significant seismic event they undergo low damage, thus requiring reinforcement re-tensioning or reinforcement replacement, which is fast and clean.
