Title: Simulation and Validation of Structural Models
Abstract: There has been significant recent work on development of simulation methodology and validation techniques for understanding the behavior of large structures – buildings, bridges, dams, etc. These efforts are aimed at designing structures that are robust to natural excitations (earthquakes, floods, high winds) as well as human factors (explosions, fire). The eventual goal of these efforts is to understand why structures fail and how to mitigate these failures. In this chapter, we describe our recent efforts aimed at developing complex structural models, using them to understand structural failure (the 9/11 collapse of the Twin-Towers), and experimental efforts aimed at calibrating and validating computational models. In particular, we demonstrate that using high-performance computing platforms, powerful simulation engines, high-resolution geometric models, and accurate materials models, we can gain considerable understanding of structural response to excitations. We also describe the complexity of experiment design and data acquisition from experiments.
