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 ...
Recent earthquakes around the world have demonstrated that steel moment-frame buildings designed based on older seismic provisions are seismically deficient. To enhance the seismic performance of these buildings, a new seismic retrofit system has been deve ...
In several countries of central Europe, many modern residential buildings are braced by reinforced concrete (RC) and unreinforced masonry (URM) walls coupled with RC slabs. Such mixed constructions, in fact, behave better under seismic loading than buildin ...
Abstract Performance-based earthquake engineering necessitates the development of reliable nonlinear analysis models that are able to simulate the behavior of structures from the onset of damage through collapse. These models provide engineering demand par ...
In several countries of moderated seismicity, with the re-evaluation of the seismic hazard most unreinforced masonry (URM) buildings with reinforced concrete slabs failed to satisfy the seismic design check. A possible seismically retrofit solution consist ...
Fragility functions that permit the estimation of damage in pre-1994 welded flange bolted-web beam-to-column moment connections are developed. The fragility functions provide estimates of the probability of yielding and of experiencing fracture as a functi ...
Reinforced concrete (RC) walls are frequently used as lateral stiffness and strength-providing members in RC buildings. If well detailed and designed according to capacity design rules, RC walls can lead to a very robust behavior and stable cyclic response ...
Cultural heritage buildings were typically built without considering seismic action and are therefore potentially susceptible to earthquake damage. The performance states and protection objectives developed for ordinary buildings are not directly applicabl ...
Design recommendations for longitudinal reinforcement layouts of reinforced concrete (RC) walls have been derived from plane section analyses. Such an analysis generally favours wall layouts with boundary elements containing large amounts of vertical reinf ...
