ABSTRACT

In 2004, the first static test using polymer grid as structural reinforcement for earthen walls was performed at the Structures Laboratory of the Pontifical Catholic University of Peru (PUCP). In 2005 the first dynamic test using the same reinforcement showed excellent results in substantially reducing the seismic vulnerability of earthen buildings. During the period between 1984 and 1990, seismic simulation tests using the unidirectional shake table of the Structures Laboratory at PUCP were performed on 3/4 scale adobe building models without roof, and with and without internal cane reinforcement. Plan dimensions of the table are 4.40 m x 4.40 m with a maximum model weight capacity of 14 tons, just enough to test a square, four orthogonal wall traditional model with symmetrical openings. In accordance with the International Decade for the Reduction of Natural Hazards, PUCP focused experimental work on existing houses, with the objective of reducing the seismic vulnerability of earthen buildings.
