HYSTERETIC MO DEL AND SEISMIC VULNERABILITY OF F ERROCEMENT HOUSES
In developing countries the lack of adequate housing for low income population is a critical problem. The frequency of strong seismic motions in some of them renders the problem even more critical. As a common aftermath of a earthquakes is a large destruction of nonengineered houses. Ferrocement panel housing has been proposed as a building technique for coping with this problem as a low cost solution. In this paper the results of a experimental analysis on 3D models of ferrocement houses at a 1:1 scale is reported. The purpose of the research is twofold: First, to analyze the overall behavior of this building type, its hysteretic response and to fit a Bouc-Wen-Baber-Noori model for it using system identification techniques. Second, to calculate vulnerability matrices for a certain seismic region of Colombia (having a design acceleration equal to 0.25 g), in order to promote the system as a economical as well as safe solution for lowincome inhabitants. The results show that in spite of the stiffness and strength degradation exhibited by the lab model under strong lateral displacements, the vulnerability for the target region is rather low.
