NIST has released videos and data from fire tests on cold-formed steel-framed shear walls, lightweight building materials used extensively in low-rise to mid-rise commercial construction. The shear walls help transfer horizontal forces, such as those that arise from wind or earthquakes, down to the foundation. The NIST tests included a simulated kitchen fire followed by earthquake-like mechanical loads to test the walls’ structural integrity. These studies can help engineers and fire professiona
