Comportamiento sísmico y alternativas de rehabilitación de edificaciones en adobe y tapia pisada con base en modelos a escala reducida ensayados en mesa vibratoria

Abstract

This paper summarizes the main results of a research project carried out to determine the main characteristics and mechanical properties of the structural elements that conform the earth made constructions, and to propose seismic rehabilitation alternatives according to the seismic hazard and characteristics of this kind of structures in Colombia. The proposed seismic rehabilitation alternatives consist of reinforcement with wire mesh covered with lime based mortar, and confining reinforcement with wooden elements. These alternatives were subjected to a series of tests on small specimens, full scale walls loaded on both directions, shaking table tests on 1:5 scale models and cyclic horizontal loading on 1:1.5 house models. The results of the research allow to establish advantages and disadvantages for the rehabilitation alternatives studied. Considering the high seismic vulnerability of earth made constructions, the confining reinforcement with wooden elements was found to be a promising alternative to reduce the seismic risk of this type of constructions.
