A model-based data-interpretation framework for post-earthquake building assessment with scarce measurement data

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland

Recent earthquake events throughout the world have once again exposed the vulnerability of buildings with respect to earthquakes. It is unlikely and unsustainable to design and - especially in regions with low-to-moderate seismic hazard – to retrofit all b ...

Vulnerability Assessment of Buildings in Ranau Township: Methodological Design

Pierino Lestuzzi, Noor Sheena Herayani Harith

Structural damage usually happens during earthquake events. This had caused damage of properties and even worse, loss of lives. Usually, the greatest losses were not caused by the quake specifically, but rather because of the fall of the structures. The vu ...

Measurement-based support for post-earthquake assessment of buildings

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland

After a damaging earthquake, assessment of the residual seismic capacity is required for large parts of the building stock. Increased vulnerability of structures together with the threat of immediate aftershocks call for rapid and objective decision making ...

Application of Association Rules to Determine Building Typological Classes for Seismic Damage Predictions at Regional Scale: The Case Study of Basel

Pierino Lestuzzi, Yves Sylvain Gilles Reuland, Lorenzo Diana

Assessing seismic vulnerability at large scales requires accurate attribution of individual buildings to more general typological classes that are representative of the seismic behavior of the buildings sharing same attributes. One-by-one evaluation of all ...

A programmable low-power ADC interface for an ISFET sweat sensor used in a wearable multi-sensing system

Maher Kayal, Evgenia Voulgari, François Krummenacher

An application specific integrated circuit (ASIC) named ANTIGONE (ANalog To dIGital cONvErter) was designed in AMS 0.35 mu m technology to interface with four Ion-sensitive field-effect transistor (ISFET) sensors and perform real-time monitoring of some bi ...

Structural Resilience through Model-Based Data Interpretation: From Building to City-Scale Post-Seismic Assessment

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland, Lorenzo Diana

Earthquake-design approaches in regions with low to medium seismic hazard often focus on the protection of inhabitants. Therefore, some structural damage is accepted. In addition, large parts of the building stock have usually been built without considerin ...

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

Dimitrios Lignos, Seong-Hoon Hwang

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 ...

Probabilistic Risk-Based Performance Evaluation of Seismically Base-Isolated Steel Structures Subjected to Far-Field Earthquakes

Aryan Rezaei Rad

The performance of base-isolated steel structures having special moment frames is assessed. The archetypes, which are designed per ASCE/SEI 7-2016, are simulated in the Finite Element (FE) computational platform, OpenSees. Adopting nonlinear dynamic analys ...

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 ...

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 ...
