The 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 ...
EEME2023A Probabilistic Physics-Based Seismic Hazard Model for the Alborz Region, Iran
The seismic activity rate is one of the most significant factors in seismic hazard modeling. Although it is usually estimated from observed seismicity, a complete picture of the possible earthquakes is not always available since catalogs of the observed ea ...
SEISMOLOGICAL SOC AMER2022Modelling of in-plane seismic behaviour of one-way steel or timber jack arch floors in existing buildings
The type of floor system has a decisive role in the seismic performance of unreinforced masonry buildings. The in-plane stiffness of the floors has to be adequately represented in the numerical modelling of existing buildings, as it can influence their sei ...
2022Seismic response of historical masonry buildings and aggregates - large-scale experimental testing and macro-element modelling
The seismic analysis of existing unreinforced masonry buildings is a challenging task, troubled by different sources of material and modelling uncertainties. The historical heritage value of a building can further complicate the assessment and design of re ...
EPFL2022Seismic 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 ...
2022Historical Development and Seismic Performance of Unreinforced Masonry Buildings with Vertical Extensions in the City Centre of Barcelona
This paper presents the historical development of the vertical extensions of unreinforced masonry buildings in the Eixample district of Barcelona and their impact on the seismic behaviour. Existing masonry buildings of Eixample present significant seismic ...
TAYLOR & FRANCIS INC2022Long-term triggered seismicity on the Mosha fault by Damavand volcano, Iran: Implications on the seismic hazard of Tehran metropolis
The seismic history of the Mosha fault, the largest and most active fault of Eastern Tehran metropolis, and its relation to the Damavand active volcano, the highest mountain in the Middle East, is investigated. We deduce that the central Mosha, near the Da ...
2022Seismic vulnerability assessment of free-standing massive masonry columns by the 3D Discrete Element Method
Free-standing masonry column is a recurrent typology of built cultural heritage. Usually raised without seismic design, columns are subject to intense rocking and overturning under strong ground motions. In this paper, a strategy to assess their seismic vu ...
ELSEVIER SCI LTD2021Fragility Assessment of Beam-Slab Connections for Informing Earthquake-Induced Repairs in Composite-Steel Moment Resisting Frames
Dimitrios Lignos, Hammad El Jisr
Earthquake loss estimation in composite-steel moment resisting frames (MRFs) necessitates a proper estimation of the level of damage in steel beam-to-slab connections. These usually feature welded headed shear studs to ensure the composite action between t ...
2021Uplift mechanics of unanchored liquid storage tanks subjected to lateral earthquake loading
Motivated by the seismic response of unanchored liquid storage tanks, their uplift mechanism under strong lateral loading is examined. Using three-dimensional finite element models, nonlinear static analysis is conducted to define the moment-rotation relat ...
