Abstract

Nonstructural systems constitute a significant portion of the total property of typical buildings. Recent earthquakes have conclusively demonstrated that nonstructural damage results in significant loss of property and function with major catastrophic impact on communities. As part of the NEESR-GC project on the ”Simulation of the Seismic Performance of Nonstructural Systems” and in a collaborative effort with NEES TIPS and NIED, a full-scale, five-story steel moment frame building in base-isolated and fixed-base configurations was subjected to a number of 2D and 3D ground motions using the E-Defense shake table. The building was tested under three different configurations: 1) base isolated with triple pendulum bearings (TPB), 2) base isolated with a combination of lead-rubber bearings and cross linear bearings (LRB/CLB), and 3) fixed base. For this experiment, more than 800 sq-ft of suspended ceiling with lay-in tiles and 3 sprinkler branch lines were installed on the 4th and 5th floors of the building. This paper presents some of the preliminary observations related to the response of nonstructural systems from these experiments.
