Nonmodel-based framework for rapid seismic risk and loss assessment of instrumented steel buildings

This paper proposes a nonmodel-based framework for estimating story-based engineering demand parameters (EDPs) in instrumented steel frame buildings with steel moment-resisting frames (MRFs). The proposed framework utilizes a wavelet-based damage-sensitive ...

Evaluation of force-based and displacement-based out-of-plane seismic assessment methods for unreinforced masonry walls through refined model simulations

Katrin Beyer, Michele Godio

The performance of force-based and displacement-based seismic assessment methods for the life-safety limit state check of out-of-plane loaded unreinforced masonry walls is evaluated on the basis of refined numerical simulations. For this purpose, a discret ...

Effect of damping models on the simulation of seismic axial forces in a reinforced concrete bridge pier

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Manuel Jordan

Post-reconnaissance findings after recent earthquakes have shown that the effect of the vertical acceleration component of the ground motion can be more damaging than typically considered thus far, particularly in near-field regions where the ratio of vert ...

Seismic displacement-demand and urban damage distribution: the impact of different methods on vulnerability assessment

Pierino Lestuzzi, Yves Sylvain Gilles Reuland, Lorenzo Diana, Stefano Podesta

This paper addresses seismic vulnerability assessment at urban scale. Particularly, it focuses on the differences in damage distribution obtained from the application of several simplified methods for displacement demand determination. The results obtained ...

Probabilistic mechanics-based loss scenarios for school buildings in Basel (Switzerland)

Pierino Lestuzzi, Clotaire Michel, Pia Hannewald

Developing earthquake scenarios for cities in areas with a moderate seismicity is a challenge due to the limited amount of available data, which is a source of large uncertainties. This concerns both the seismic hazard, for which only recordings for small ...

Proposed methodology for earthquake-induced loss assessment of instrumented steel frame buildings: building-specific and city-scale approaches

Dimitrios Lignos, Seong-Hoon Hwang

The performance-based earthquake engineering framework utilizes probabilistic seismic demand models to obtain accurate estimates of building engineering demand parameters. These parameters are utilized to estimate earthquake-induced losses in terms of prob ...

Earthquake-induced loss assessment of steel frame buildings with special moment frames designed in highly seismic regions

Dimitrios Lignos, Seong-Hoon Hwang

This paper discusses an analytical study that quantifies the expected earthquake-induced losses in typical office steel frame buildings designed with perimeter special moment frames in highly seismic regions. It is shown that for seismic events associated ...

Measurement-supported performance assessment of earthquake-damaged concrete and masonry structures

Yves Sylvain Gilles Reuland

As demonstrated by recent events in Italy, New-Zealand, Haiti, and Nepal, earthquakes continue to pose threats to civil infrastructure, including buildings. For a long time seismic ultimate limit states have not been considered in design codes for regions ...

Seismic retrofit of cultural heritage buildings – when less is more

Katrin Beyer, Francesco Vanin, Michele Godio, Andrea Penna

In 1356, Basel was subjected to an earthquake with an estimated magnitude of 6.6; it is the largest known historical earthquake in central northern Europe. During this earthquake and the fire that followed large parts of Basel were destroyed. Such an event ...
