Resistencia sísmica del suelo-cemento postensado en construcciones de baja complejidad geométrica

Abstract

This article shows the research and development of a structural-building technique based on soil, which offers the improvement of earthquake resistance within an acceptable range (0.8g). The so-called soil-cement material was investigated and developed in laboratory. Then, a building technique based on rammed soil on post-tensioned soilcement was developed. Two physical prototypes at a 1:6 scale were built, that were subject to strength tests in the Laboratory of the Civil Works Department of the UTFSM to assess their performance under seismic stress. Test results were satisfactory, since both models resisted Kobe earthquake (0.8g) simulations with no signs of collapse. It is thought that this model could be applied in the construction of new buildings with low geometric complexity after the earthquake of February 2010 in Chile.
