Resumen
Abstract
Self-built houses in Bogota with unreinforced masonry make up approximately 48 to 60%
of the houses in the city. Due to the low structural performance of this system and
the high probability of an earthquake occurrence, it is necessary to reinforce these
dwellings to avoid serious injuries to the inhabitants, material losses and the
impossibility of using the spaces. Although there are multiple reinforcement methods
currently in use, technical and economic limitations in informal contexts require
alternatives to conventional methods. By using of destructive axial compression
and diagonal tension tests, the feasibility of using polypropylene bands, normally
used for packaging in the load-bearing sector, to reinforce unreinforced masonry walls
was investigated, with the objective of facilitating construction processes and
increasing the applicability of these reinforcements in self-built houses. Positive results
were obtained especially in the performance of the walls in diagonal tension, in the
increase of time to collapse and in the confinement of rubble after
fragile failure of the masonry.
