“…Research efforts quantified the benefits of using viscous dampers for reducing damage in non-structural components of building structures [9,10]. Notable experimental studies that validated the superior seismic performance of steel MRFs with viscous dampers include the full-scale shaking table tests conducted by Kasai et al [11] and the large-scale real-time hybrid simulations conducted by Dong et al [12]. ASCE 7-10 provides a detailed design procedure for buildings with passive dampers within the framework of the traditional response spectrum and equivalent lateral force methods of analysis [13].…”

Previous research showed that steel moment-resisting frames (MRFs) with viscous dampers may experience column plastic hinges under strong earthquakes and highlighted the need to further assess the efficiency of capacity design rules. To partially address this need, three alternatives of a prototype building having five, 10 and 20 stories are designed according to Eurocode 8 using either steel MRFs or steel MRFs with dampers. Incremental dynamic analysis (IDA) is conducted for all MRFs and their collapse resistance and plastic mechanism is evaluated. The results show that steel MRFs with dampers are prone to column plastic hinging in comparison to steel MRFs. The steel MRFs with dampers are then iteratively re-designed with stricter capacity design rules to achieve a plastic mechanism that is approximately similar to that of steel MRFs. The performance of these re-designed steel MRFs with dampers indicates, that overall, enforcement of stricter capacity design rules for columns is not justified neither from a collapse resistance or a reparability perspective.

“…The results of the floor acceleration PSDM along with the original case ( ) are shown in Figure 15 and Table 5. Studies have shown that passive dampers are cost effective in reducing both story drift level and floor acceleration demand (Dong et al 2016) and could be considered as possible alternative retrofit strategy. Using the results for the PSDM for floor acceleration, the fragility of the cabinets for these different cases can be compared.…”

This paper presents the seismic fragility assessment of the Smithsonian Institute Museum Support Center (MSC), which sustained appreciable damage during the 2011 Virginia Earthquake. A three-dimensional (3D) finite element model (FEM) for the building was created and validated using measured dynamic characteristics determined from field vibration test data. Two suites of bi-directional ground motions at different hazard levels were applied to the FEM to generate fragility curves for structural as well as nonstructural (storage cabinets) damage. The effect of brace yielding strength on structural and nonstructural damage is also investigated to provide recommendations for future retrofit. The fragility curves show that the spectral acceleration to cause structural damage to the building is not high. Due to low seismicity, however, the probability for the structure to be damaged at the design basis earthquake is small. Nevertheless, the probability for non-structural damage is considerable, which is an important issue related to the seismic performance of the building.
