Analysis of the stresses obtained in adobe walls without reinforcement against lateral loads obtained through modeling in SAP 2000

Abstract

When talking about the techniques of collection, elaboration and construction of adobe and in general of constructions with earth, there is always a great variety of construction techniques, and composition in the blocks that vary according to the region and culture [1], which generates a great uncertainty, and causes that, at present, although we have decree 2113 of 2019, we do not have clarity as to a method and characteristics universally valid and accepted in our country. It is for this reason that in this work we show the modelling of a series of type walls by means of the SAP 2000 program for which applying a static linear analysis for finite elements and an analysis of stresses the service limit states given for a series of walls of different composition are determined, which showed that the percentage of failure for adobe walls is 40% under the given methodology, under this threshold it was determined that the element can be in service and have functionality, exceeding this value it is denoted that the element will lose its functionality without entering into risk of collapse until reaching a percentage of 50%. Finally, the models are obtained with the appropriate effort analyses and design recommendations under the criteria of the results obtained, leaving the possibility of performing an experimental phase to develop the analogy with those raised in the models.
