The Center for Geotechnical Modeling (CGM) supports the idea of payload tests where independent secondary experiments can be completed relatively simply and efficiently within the context of a larger primary experiment. The CGM will facilitate payload projects by supporting collaboration and interaction between the multiple parties involved, as described herein.
The confined space, high g-field, and dense complexity of typical experiments on the 9-m centrifuge means that accommodation of payload projects generally increases the complexity of the primary experiment and puts additional burden on the primary project's PI and researchers. For this reason, the successful execution of a payload project will require active cooperation between the lead experiment team and the payload experiment team, along with support from the sponsors of both projects, the NHERI Network Coordination Office (NCO), and the CGM. This expectation of cooperation will likely be outlined contractually in a multi-participant research agreement.
A list of NSF-sponsored projects using the CGM and the upcoming test schedule at the CGM are listed online by the NCO. Primary project PIs share the details of their experiment with DesignSafe-CI for posting on the NHERI website so that the community is informed of opportunities for payload projects.
The CGM and the primary project PI can review payload proposals only for technical feasibility and financial impact on the existing work.
