Out of all the connections, the plasterboard to perimeter channel connection by drywall screw was found to be brittle and vulnerable under monotonic and cyclic tension. Multilinear (nonlinear) connection models were derived from the median envelop curves considering their initial and post-yield behaviors. The results were presented in terms of monotonic and cyclic failure states and envelope curves. The critical connections were classified by considering the components' connections to supporting structure and ceiling: connections to perimeter or perimeter channel, connections to roof, and connections to ceiling.

In this paper, results are presented for a series of monotonic and cyclic tests conducted on three experimentally evaluated ceilings connection sub-assemblages at a slow cross-head speed of 0.5 in.

This helps in deriving the mechanical behavior and also in developing alternative or new installation schemes. A fragility-based direct design approach is suggested based on the state-of-the-art review: nonstructural details could be designed, manufactured, or selected specifically to target desired tailored fragility curves representing targeted (multi)performance levels.Ī feasible alternative to evaluating the seismic performance of the suspended ceiling by expensive shake table testing is to analyze the appropriate numerical/analytical models that are incorporated with the components and connections nonlinear behavior. Furthermore, references to innovative low-damage technologies are provided, and traditional (i.e., construction practice) systems were compared with low-damage components in terms of fragility.

Seismic damage states were described and literature data were collected to build fragility domains for different nonstructural archetypes. Focusing on architectural elements (facades, partitions, and ceilings), this paper provides a state-of-the-art review of fragility functions.

Due to increased awareness of these issues, in recent decades substantial research efforts have been dedicated to the study of nonstructural seismic behavior. Moreover, the failure of these elements can represent a potential life-safety threat for occupants and pedestrians. Nonstructural damage occurs at low to moderate seismic intensities, heavily contributing to downtime and overall financial loss. These are also available in 60 different colors and hand-faux finishes.Ĭeiling Grid for Suspended ceilings: 15/16" 60 Colors to choose from:ġ2' Main Runner: $12.80 each 12' Wall Molding: $9.90 eachĢ' Cross Tee's: $4.10 each 4' T-Grid: $6.Nonstructural components typically are not designed for seismic loads, yet their behavior can affect the postearthquake building functionality significantly. Our drop-in ceiling tiles are available in 24in x 24in sizes, finished and unfinished in 30 different patterns. This grid system is installed first and drop-in ceiling tiles are simply “dropped-in” to the openings in the grid to actually form the ceiling. Suspended ceilings require a supporting metal grid that holds the tiles or panels that form the suspended ceiling. Suspended (or drop) ceilings are usually installed a few inches beneath an actual ceiling and provide a good way to hide equipment, plumbing and wiring, especially in commercial and industrial settings or in basements.
