Seismic Simulation of an Integrated Ceiling-Partition Wall-Piping System at E-Defense. II: Evaluation of Nonstructural Damage and Fragilities

Seismic analysis, design, and installation of nonstructural components and systems � background and recommendations for future work

“…Nonstructural components incorporated within the test building encompassed an integrated of suspended ceilings, partition walls, and sprinkler piping subassemblies on each of the upper two levels of the building (Soroushian et al, 2016) as well as a full-story precast concrete cladding 3D panel and flat panel that together represented a corner subassembly (McMullin et al, 2012). The sprinkler piping subassemblies installed in the upper two stories were nearly identical in configuration on each story.…”

“…The subassembly at each story included approximately 300 feet (90 m) of partition walls, 900 square feet (83.6 m 2 ) of suspended ceiling with lay-in tiles, and fire sprinkler piping with a riser pipe, a main run, and three sprinkler branch lines that included sprinkler drops as shown in Figure 6-7a and Figure 6-7b. Additional details of the sprinkler piping systems are available in Soroushian et al (2016). In addition, two areas enclosed by self-standing partial height partition walls were designated as an office room at the fourth floor and a hospital room at the fifth 6-14 6: Simulated Seismic Testing of GCR 17-917-44 Nonstructural Components and Systems floor and are shown in Figure 6-7c and Figure 6-7d, which were used to stage a variety of furniture and other unattached items (Guzman and Ryan, 2015b).…”

Shake table tests on standard and innovative temporary partition walls

“…

Shake table tests are performed on temporary internal partitions for office buildings. Several research studies can be found in the literature concerning the seismic assessment of nonstructural components, for example, [7-14] among many others; many research activities focused on the experimental assessment for the seismic performance of components; some numerical studies were also developed based on such experimental campaigns.Some studies dealt with the assessment of the performance of lightweight partition systems (and light office furniture) [15][16][17]. A steel frame is designed to exhibit relative displacements which typically occur at a given story of ordinary buildings.

“…Some studies dealt with the assessment of the performance of lightweight partition systems (and light office furniture) [15][16][17]. Extensive experimental campaigns were conducted at the State University of New York at Buffalo and at the University of Nevada [11,18] However, the lack of previous studies on the seismic performance of temporary (mobile) internal partitions is clearly denoted in literature.…”
