More Description

This publication summarizes the methodology, and presents the conclusions of the modeling phase of the Seismic Retrofitting Project (SRP) carried out by TecMinho, University of Minho, Portugal. Using four Peruvian buildings representative of typologies of historic earthen construction in Latin America, the SRP relies on traditional construction techniques as well as state-of-the-art methods to design and test easy-to-implement seismic retrofitting techniques and maintenance programs to improve the structural performance of earthen historic buildings in Peru and other countries in Latin America.From 2015 until 2017, the University of Minho developed advanced numerical models to understand the structural behavior of the SRP buildings. These models were also employed to validate the retrofitting techniques designed by the SRP partners and consultants. The report provides a review of advanced structural analysis techniques, guidance for finite element modeling users, an overview of constitutive models, and two examples (one of validation and one of application). The publication intends to help professionals and researchers, in the field of structural engineering, with the assessment of historic earthen structures using advanced numerical modeling techniques.This publication is part of a series within the SRP that intends to provide professionals and researchers in the field of structural engineering with a methodology for the assessment of historic earthen structures using advanced numerical modeling techniques. The other reports that are part of the modeling phase are Modeling of Prototype Buildings and Simplified Calculations for the Structural Analysis of Earthen Historic Sites.
