The 12th ACHISINA Conference was held at the Universidad Austral campus in Valdivia from April 3 to April 5, 2019.
The conference is organized every four by the Chilean Association of Seismology and Earthquake Engineering (ACHISINA) and is one of the main conferences in Latin-America on earthquake engineering.
In this version of ACHISINA Conference, professor Astroza presented the following seven papers:
- Shake table tests of a full-scale five-story building
- Dynamic properties of a full-scale 5-story base-isolated R/C building tested on a shake table
- Dynamic characterization of a full-scale 5-story R/C seismically damaged building specimen
- Dealing with modeling errors in nonlinear mechanics-based finite element model updating
- Damage identification in civil structures by using nonlinear finite element models and Bayesian methods
- Intensity attenuation curves for Chile considering earthquakes from 1906 to 2016
- Nonlinear finite element model of the Marga-Marga bridge and its calibration using data recorded during the Maule 2010 earthquake
In addition, Professor Astroza co-authored the following five papers led by our collaborators from the Universidad de Chile, professors Francisco Hernandez, Cesar Pasten, and Felipe Ochoa-Cornejo.
- Geotechnical aspects of the 2017 Mw 7.1 Puebla-Morelos Earthquake
- Dynamic response of the Santiago basin: Numerical modeling of a unidimensional and bi-dimensional geotechnical profile
- Effect of the pseudo-static component on structures under multiple support seismic excitation
- System identification of the superstructure of base isolated buildings using a sub-structuring approach
- Reasons for building collapses during the Puebla-Morelos (Mw 7.1) Earthquake
