“…Comprehensive studies investigated seismic performance of both traditional and innovative partitions. [26][27][28][29] More recently, the research activity focused on hospital equipment. A complete typical ambulatory room with freestanding components was tested unidirectionally for the dynamic identification and seismic performance evaluation.…”

Summary An experimental investigation of hospital building equipment is presented. Dynamic properties and seismic performance of typical ambulatory freestanding cabinets are assessed by unidirectional and bidirectional shake table tests, also considering the presence of internal partitions and cabinet contents. Vulnerability analysis is performed according to the most recent and reliable assessment methods, evaluating the influence of different parameters of the sample cabinets. The performance criteria referred within this research are the limit states reached by the specimens (ie, rocking and overturning) and by their contents (ie, overturning and breaking). Fragility curves are evaluated for the components and the contents, considering both acceleration and velocity intensity measures, and also using dimensionless intensity measures developed in recent studies. The outcomes of the present study confirm the findings of previous laboratory tests and numerical simulations carried out by the same authors and provide a further insight for the reliable seismic performance assessment of hospital cabinets and their contents.

“…At this stage, the availability of fragility functions for both structural and non-structural elements is necessary. In the literature, few experimental investigations are available for non-structural elements [4][5][6][7]. For this reason, many fragility functions are based on expert judgments.…”

In the last years an increasing interest has been addressed to the assessment of the expected mean annual losses of single buildings as well as of building portfolio(s). Field observation of damage/failure in the aftermath of past earthquakes demonstrates that the losses related to the non-structural elements could significantly exceed the structural losses. At the same time, it is worth noting that the damage related to the non-structural elements could affect the functionality of the buildings and critical facilities. Based on these considerations, a detailed assessment of the expected annual losses requires data both on the structural and non-structural elements. In comparison to structural elements and systems, however, there is much less information and experimental data to undertake the assessment and design of non-structural elements for multiple-performance levels. Shake table testing could thus be very useful to assess the seismic performance of non-structural elements and to achieve the required information for loss estimation studies. In this paper, the results of shake table testing of acceleration-sensitive non-structural elements are presented. Equivalent single degree of freedom numerical models of the analyzed acceleration-sensitive non-structural element was developed using the results of the tests and a performance evaluation was carried out.

“…In particular, the seismic response of lightweight steel drywall partitions tested in isolated configuration was evaluated under dynamic and/or in-plane or out-of-plane quasi-static loading conditions (Freeman, 1 Lee et al, 2 Memari et al, 3 Restrepo and Bersofsky, 4 Peck et al, 5 Araya-Letelier and Miranda, 6 Retamales et al, 7 Tasligedik et al, 8 Petrone et al, 9 and Swensen et al 10 ). Furthermore, the interaction between lightweight steel drywall partitions and structural elements and/or other nonstructural building components, ie, outdoor façades and suspended ceilings, was investigated by means of shake table tests on full-scale one/multistorey structures completed with ceiling-partition systems (Rihal, 11 Filiatrault et al, 12 McCormick et al, 13 Matsuoka et al, 14 Magliulo et al, 15 Wang et al, 16 Jenkins et al, 17 and Petrone et al 18 ).…”

“…The effect of partition walls on the overall performance of a structure during a seismic event was investigated by means of cyclic tests 2,8 and dynamic tests on shaking tables. [13][14][15][16][17][18] The analysis of these parameters highlighted that the contribution of partition walls in lateral strength, secant stiffness, and dynamic properties, ie, fundamental vibration period and damping ratio, is not negligible compared with that of structural supporting system.…”

Summary An experimental program was performed for evaluating the seismic response and fragilities of nonstructural lightweight steel drywall partitions, also considering the interaction with structural elements and other nonstructural building components, ie, outdoor façade walls. Therefore, in‐plane quasi‐static reversed cyclic tests were carried out on 8 specimens of indoor partition walls infilled in a frame and on 4 specimens of indoor partition walls connected at its ends with transversal outdoor façade walls. Constructive parameters under investigation include type of connections used for connecting the indoor partition walls to the surrounding elements, stud spacing, type of sheathing panels, and type of jointing finishing. The effect of the constructive parameters on the lateral response in secant stiffness and strength is examined. Furthermore, the main damage phenomena observed during the tests are reported and associated to 3 damage limit states distinguished for the required repair level for the tested partition walls. Fragility curves are used for the experimental assessment of seismic fragility of the tested specimens, in accordance with the interstorey drift limits required by the European code. Finally, the quantitative estimation of the repair action costs starting from the damage observation is also developed. The obtained results could be considered a starting point for developing the in‐plane seismic design assisted by testing of lightweight steel drywall partition walls.
