Nucleation, propagation, and scale dependence of laboratory frictional ruptures; implications for earthquake mechanics.
Earthquakes are natural phenomena that cause ground shaking and damage to people and infrastructures. Despite significant progress achieved in understanding how earthquakes start, propagate, and arrest, many aspects of their physics and mechanics remain no ...
EPFL2023The use of ductile steel fuses for the seismic protection of acceleration sensitive non- structural components: Numerical and Experimental verification
Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady
Recent seismic events have showcased the vulnerability of non-structural components to even low- or moderate-intensity earthquakes that occur far more frequently than design-basis ones. Thus, community-critical buildings, such as hospitals, telecommunicat ...
EEME2023Background Rejection in Two-Photon Fluorescence Image Scanning Microscopy
We discuss the properties of signal strength and integrated intensity in two-photon excitation confocal microscopy and image scanning microscopy. The resolution, optical sectioning and background rejection are all improved over nonconfocal two-photon micro ...
MDPI2023A 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 ...
2022Seismic 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 ...
2022An 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 ...

Dimitrios Lignos, Andronikos Skiadopoulos
This paper summarizes preliminary findings of nonlinear simulations aiming to quantify the seismic demands of codecompliant steel MRFs with variable panel zone targeted shear distortions, 𝛾!. The probability of beam fractures is explicitly considered in th ...
Earthquake Engineering Research Institute2022Analytical Studies in Support of an Improved Approach to the Design of Acceleration-Sensitive Nonstructural Elements
Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady
This paper summarizes a series of analytical studies that were conducted in connection with an improved approach for the design of acceleration-sensitive nonstructural elements. In the new approach, bracing to secure nonstructural elements to the structure ...
Applied Technology Council, Sponse2022Experimental Study to Validate an Improved Approach to Design Acceleration-Sensitive Nonstructural Components
Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady
Nonstructural components in buildings can be subjected to very large acceleration and deformation demands during earthquakes. This is particularly true for flexible components that are tuned or nearly tuned to one of the modal frequencies of the supporting ...
Applied Technology Council, Sponse2022A new perspective on the punching resistance of edge columns with and without shear reinforcement applying refined measurement techniques
Aurelio Muttoni, Diego Hernández Fraile
Despite edge columns being instrumental components of flat slabs, most punching research has focused on internal connections. Several particularities of edge columns, such as load eccentricity and moment transfer, require additional experimental investigat ...
