News & Events

January 2016 Website updated and project close out

As of December 2015 the CFS-NEES project is complete. This website has been updated a final time so that it may remain as a permanent repository for the research. The experimental data is also curated with NEES and is transitioning from to under the NSF NHERI initiative (new in 2015). The PIs and project team send their thanks to the vast number of participants and sponsors who made the project possible.

Septmber 2014 Website updated

Full-scale testing is complete. Computational modeling is underway and will be complete in the Fall of 2014. Publications have been updated. It is intended that this page will provide an archive for the CFS-NEES project, along with the materials available at the NEESHub, but this site is no longer seeing regular updating.

June 2013 Phase 1 testing completed at UB's SEESL lab

Full-scale testing and related construction are ongoig at the SEESL lab at the University of Bufalo in the Summer of 2013. Graduate student Kara Peterman is at the SEESL lab for the summer and providing regular (blog) updates of the progress at The Phase 1 testing concluded with a shake table test of the CFS-NEES building under the full-scale Canoga Park record from the 1994 Northridge Earthquake.

January 13, 2013 New report released and all publicatons updated

The test report on fastener cyclic resting (RR)4) is posted and all publications related to the project have been updated in Publications.

December, 2012 Testing at UB-NEES to begin April 2013

The CFS-NEES full-scale testing will begin at UB-NEES starting 15 April 2013. Updates and links on the progress of the full-scale testing will be provided as the work progresses in the Spring and Summer of 2013.

June 22, 2012 New report on shear wall testing released

The test report on shear wall tests conducted as part of the CFS-NEES project is now available in Publications.

May 17, 2012 Updated report on CFS-NEES model building

The building design narrative is now updated to version c. The updates include 1. clarification of the shearwall, chord studs and holddown designs for systems with mixed field and boundary stud thickness and yield points. 2. The stiffening detail for the HSS ‘foundation’ at holddowns is now included in the drawings (Appendix 5), and 3. Appendix 7 including the analysis and discussion of the rigid diaphragm modeling. The updated report is now available in Publications.
