“…The ways to define the damage thresholds are numerous: one of these is defined as a function of the two points representative of the pushover curve, that is the yielding displacement D y and the ultimate one D u [23]. The approach proposed in this paper, instead, correlates the limit states at appropriate drift values, in line with the provisions of other scientific researches on the same topic [18]. As a seismic parameter (intensity measure I) the spectral displacement S d has been adopted, because the capacity curves have been converted into the ADRS format in order to be able to compare in an easy manner the capacity values with those of the seismic demand represented by the response spectrum.…”

“…This value is taken on the basis of the FEMA 356 regulations [17], which are more complete and detailed than the Eurocode 8 provisions. This choice has been justified, besides, by the chance to compare the results with those proposed by other scientific researches dealing with similar topics [18]. The structure capacity in terms of displacement has been carried out on the basis of the FEMA legislative provisions, which refer to predefined maximum values of the inter-story drift: 0.0075 for immediate occupancy (IO), 0.025 for life safety (LS) and 0.05 for near collapse (NC).…”

Introduction:\ud The recent L’Aquila (2009) and Emilia-Romagna (2012) Italian earthquakes have highlighted the vulnerability of recently erected\ud buildings, with particular reference to industrial ones. Although steel buildings have usually demonstrated a good behaviour under\ud earthquakes, with limited damages and rare cases of collapse, they still represent a structural typology at risk due to the significant\ud exposure connected to the importance of the resources they host.\ud Methods:\ud In the paper a parametric study on several industrial steel buildings, different for typology, geometrical dimensions, seismic zones\ud and snow geographic areas, has been done through pushover analyses.\ud Results and Conclusion:\ud The results have allowed to plot vulnerability curves, which have been compared to seismic fragility curves derived from literature\ud observational studies. The comparison among curves has allowed to estimate the effectiveness of the literature fragility studies, as\ud well as to evaluate the seismic damages suffered by investigated structures under dissimilar grade earthquakes

“…Consequently, six anchors were designed and placed outside the column flanges. In addition, base plate stiffeners were added in this case, according to a typical design choice in Italy [9]. No checks in terms of rotational stiffness were carried out at the design stage.…”

The paper describes a study concerning the seismic response of some typical non‐residential single‐story older steel buildings. To this end, the design of two archetype buildings was simulated according to structural codes and standards of practice used in Italy in the 1980s‐1990s. The basic structural layout was assumed to be made of trussed portals in the transverse direction and concentric braces in the longitudinal direction. In the direction of the trussed portals, two alternative structural options were considered: (a) a pinned column base with moment action provided by the truss, and (b) a semi‐continuous column base with a pinned connection between the truss and the column top cross section. 3D finite element non‐linear models of the two case study structures were built. The model included the main frame members, some critical connections and explicit representation of fracture propagation for braces. Results from non‐linear static analysis are then presented and discussed. The paper highlights differences in the structural response due to differences in the selected design options, comparing both global and local response results.

“…However, the codified rules are written assuming unstiffened base plates. Notwithstanding, several existing structures were either designed in the past using base plates with stiffeners [4,5] or they could be strengthened more easily using stiffened plates [6,7]. Besides, there are cases where the local traditions might lend designers in continuing the use of stiffened base plates.…”

Column base plate connections are used widely. Their design is currently codified by Eurocode 3, though with explicit consideration of only base plates without stiffeners and subjected to a proportional loading path. However, both new and existing steel structures might have stiffened base plates. Besides, there might be the need for analyzing the connection response for a non‐proportional loading path (e.g., increasing seismic loads and constant gravity loads). Therefore, the paper provides a contribution into the development of an analytical model for predicting the response of stiffened base plate connections subjected to a non‐proportional loading path. The paper deals with calculation of the connection rotational stiffness and moment resistance. The objective is pursued through finite element modelling and analysis. Then, the application of a proposed analytical model is shown and a comparison with the finite element analysis results is illustrated and discussed.
