Characterization of subgrid-scale dynamics for a nonlinear beam

•We investigate the utility an optimal spatiotemporal reduced order modeling framework.•A nonlinear beam under the influence of external forcing serves as a testbed.•Models are developed to account for the effects of unresolved spatiotemporal scales.•Model construction is simplified through a number...
