Description

The purpose of this sources sought notice is to conduct market research and identify potential sources of commercial equipment/services that satisfy the Government's anticipated needs. BACKGROUND The Structures Group in the Engineering Laboratory at the National Institute of Standards and Technology (NIST) performs research to enhance the ability of structures in the United States to 1) resist damage from various hazards (e.g., blast, wind, and seismic hazards) and 2) recover from and adapt to hazards that result in damage. To this end, the Structures Group is expanding upon a recently completed experimental research effort that focused on mitigating disproportionate collapse of buildings in the United States. The final phase of that effort involved experimentally testing precast concrete beam-column connection assemblies produced at 5/8 scale and that featured novel connection concepts developed by NIST researchers in collaboration with an industry review committee of Precast/Prestressed Concrete Institute (PCI) members. These assemblies were subjected to static pushdown testing that simulated a column-removal scenario for disproportionate collapse applications. The test results showed that the connection concepts were viable for use in precast concrete construction to achieve robust performance against disproportionate collapse. The current experimental research effort involves structural testing of full-scale precast concrete beam-column connection assemblies under forces that simulate those imposed by earthquakes. The assemblies will feature the previously tested connection concepts to establish whether these connections can perform adequately under various hazards acting asynchronously.
