This paper discusses the findings from a large-scale experimental program that characterized the hysteretic behavior of typical steel wide-flange columns in steel moment-resisting frames (MRFs). The test specimens were tested in a cantilever configuration ...
Nonlinear dynamic (response history) analysis is being used increasingly in design practice for the performance-based seismic design of new buildings. In contrast to nonlinear static analysis, dynamic analysis requires more explicit modeling of cyclic resp ...
Recent earthquakes in Chile (2010, M 8.8) and New Zealand (2011, M 6.3) have shown that, despite many years of extensive research and subsequent design code advancements, several modern reinforced concrete walls underperformed or even failed during these s ...
The heating energy represents 35% of total energy consumption in Switzerland, and private households 60% of this consumption. The retrofit of residential buildings is a fundamental component of local energy policies. However, questions remain unresolved fo ...
The paper presents the results of the evaluation of the seismic safety of the Ancien Hôpital de Sion, an important Swiss architectural heritage building, sited in the Canton of Valais, the region with the highest seismic hazard in Switzerland. Three-dimens ...
The unique conduction properties of condensed matter systems with topological order have recently inspired a quest for the similar effects in classical wave phenomena. Acoustic topological insulators, in particular, hold the promise to revolutionize our ab ...
As the desire for high performance buildings increases, a number of solutions to enhance the dynamic response of structures have been explored and implemented. In recent years, base isolation has become a practical and effective strategy for earthquake res ...
In modern unreinforced masonry buildings with stiff RC slabs, walls of the top floor are most susceptible to out-of-plane failure. The out-of-plane response depends not only on the acceleration demand and wall geom-etry but also on the static and kinematic ...
The paper discusses different modelling assumptions for spandrels in equivalent frame models and their effect on the global response of the wall. The topic is motivated by the following issues: i) reliable and practice oriented numerical tools constitute a ...
This paper evaluates the effectiveness of single and multi-mode nonlinear static procedures (NSPs) as well as the FEMA P58 simplified approach versus rigorous nonlinear response history analyses (NRHA) for estimating seismic demands of steel special moment ...
