The 37th International Modal Analysis Conference (IMAC) was held at the Rosen Plaza Hotel in Orlando from January 28 to January 31, 2019.

IMAC is organized every year by the Society of Engineering Mechanics (SEM) and is one of the main conferences in the structural dynamics community, including specialists from the aerospace, mechanical, and civil engineering fields. IMAC brings together people from academia, industry, government agencies, and exhibitors.

In this version of IMAC, professor Astroza presented the following three papers co-authored by former undergraduate students of our research group:

1. “System identification of a five-story building using seismic strong-motion data”, co-authored by Gonzalo Gutierrez (former undergraduate student) and Professor Francisco Hernandez and Pablo Diaz from the Universidad de Chile.

2. “Finite element model updating accounting for modeling uncertainty”, co-authored by Andres Alessandri (former undergraduate student) and Professor Joel P. Conte from the University of California, San Diego.

3. “Calibration of a large nonlinear finite element model with many uncertain parameters”, co-authored by Nicolas Barrientos (former undergraduate student) and the collaborators Professor Yong Li (University of Alberta) and Professor Erick Saavedra (Universidad de Santiago de Chile).

In addition, Professor Astroza co-authored the paper “Material parameter identification in nonlinear FE model governed by multiaxial material constitutive law using unscented Kalman filter”, led by our collaborators from the University of California, San Diego (Mukesh Ramancha, Dr. Ramin Madarshahian, and Professor Joel P. Conte).
