A probabilistic deformation-based seismic hazard model for Iran

Probabilistic seismic hazard analysis, as the most prevalent approach to evaluate earthquake hazard, is commonly based on earthquake catalogs. Although previous studies show that the recurrence time of large-magnitude (M-w > 7.0) events in Iran is more tha ...

An Inertial Uni-Axial Interferometer-Based Accelerometer for Harsh Environments

Mark Edward John Butcher, Gerard Aliana Cervera

For high-impact devices, subsequent vibrations have as much influence on the deterioration of the mechanical structure as the impact itself. To mitigate the consequences of both impacts and resulting vibrations, it is crucial to accurately understand the p ...

Seismic vulnerability of existing structures Large scale assessment of Basel city

Among natural disasters, seismic activity which can cause earthquakes is a serious risk for human activities and most importantly their lives. Seismic risk assessment requires knowledge to evaluate existing buildings and their expected response against ear ...

Uncertainties in the Seismic Assessment of Historical Masonry Buildings

Katrin Beyer, Francesco Vanin, Igor Tomic

Seismic assessments of historical masonry buildings are affected by several sources of epistemic uncertainty. These are mainly the material and the modelling parameters and the displacement capacity of the elements. Additional sources of uncertainty lie i ...

Vulnérabilité sismique à grande échelle. Typologie typique de bâtiments lausannois

Hajand Zainal

Seismic assessment of existing buildings is a very important area of research to predict the impact of an earthquake on an area. Over the years, unreinforced masonry buildings have shown to be highly vulnerable to seismic risk. Although Switzerland is cons ...

Quantifying the out-of-plane response of unreinforced masonry walls subjected to relative support motion

Katrin Beyer, Michele Godio

The supports of out-of-plane loaded unreinforced masonry walls in buildings are subjected to a motion that is filtered and amplified by the building structure and, in some cases, can be significantly different from the ground motion. Moreover, because thes ...

Assessment of the Probability of Collapse of Structures Under Earthquakes

Dimitrios Lignos

Avoidance of collapse is the most important objective in earthquake resistant design, but assessing the probability of collapse of a structure during an earthquake is technically challenging and it is computationally demanding. This paper summarizes recent ...

Damage predicting algorithms for regular RC structures

Pierino Lestuzzi, Amin Karbassi

In this paper a 2-phase decision tree algorithm is developed to qualitatively predict damage in RC buildings based on earthquake characteristics and structural properties. To this end, the structural properties considered are the natural period of the fund ...

Performance-Based Seismic Vulnerability Evaluation of Masonry Buildings Using Applied Element Method in a Nonlinear Dynamic-Based Analytical Procedure

Amin Karbassi

A thorough four-step performance-based seismic evaluation for a six-story unreinforced masonry building is conducted. Incremental dynamic analysis is carried out using the applied element method to take advantage of its ability to simulate progressive coll ...

Development of fragility functions as a damage classification/prediction method for steel moment-resisting frames using a wavelet-based damage sensitive feature

Dimitrios Lignos

Fragility functions are commonly used in performance-based earthquake engineering for predicting the damage state of a structure subjected to an earthquake. This process often involves estimating the structural damage as a function of structural response, ...
