Home : Experiment-based Simulations

Overview

The strategic objective of the simulation studies is to develop an experiment-based simulation platform that accurately evaluates response and fragilitires associated with system-level failure modes of ceiling-piping-partition nonstructural systems.
The proposed simulation framework requires modeling, analysis, and visualization of these systems, and the unique output of this will be the integration of these systems, and the unique output of this will be the integration of these concepts within a unified user computer code to evaluate system-level fragilities.

System-level fragilities require association with prescribed damage states, which are compared with physical damage states observed in the experiments. It is therefore termed an "experiment-based simulation" program.

To realize the vision of this integrated simulation framework, the following approach is proposed:

i.	Available analytical and experimental data will be reviewed and archived.
ii.	Experimentally validated analytical models of ceiling-piping-partitiion nonstructural systems will be developed using macro and/or discrete element formulations, also considering existing response data from the literature survey.
iii.	Algorithms for fragility evaluation and experimental validation of global system fragilities will be developed.
iv.	Tools will be developed for the visualization of the experimental and simulation data.
v.	Representative index-buildings will be developed and modeled to provide input into the public policy investigations.
