Nonstructural Component and System Testing Database (NIST/ATC-120)

This Nonstructural Component and System (NCS) Testing Database is referred to in the NIST report GCR 17-917-44, Seismic Analysis, Design, and Installation of Nonstructural Components and Systems - Background and Recommendations for Future Work. The database was developed for collecting the seismic response and performance of acceleration-sensitive NCSs during the simulated seismic tests and field earthquakes. The data of an individual NCS associated with a specific test are organized row-by-row, while different data entries are contained in separate columns. The data entries of the spreadsheet table, in a left-to-right order, include metadata and test results in the following categories: -Test program or earthquake: contains information about the test or earthquake short name, test type (e.g., system-level shake table test, component-level pseudo-static tests), test facility, and references. - NCS metadata: contains general descriptions of NCS type/subtype (e.g., mechanical, electrical, contents), geometry, weight, attachment details, mounting condition, frequency/period, and etc. - NCS design basis: design standard, short-period design spectral acceleration, design seismic force demand. - Target and measured response: measured acceleration of the input, building, NCSs, and floor response spectral values. - Damage state: damage states of the component, support, and anchors (e.g., none, minor, moderate, severe). Currently the database contains test results of NCSs from one system-level experimental project and three component-level projects. In addition, field observations of the response of NCSs during the 1994 Northridge earthquake are incorporated into the database.
