Deformation capacity evaluation for flat slab seismic design
Aurelio Muttoni, Lorenzo Martinelli, António Manuel Pinho Ramos, Andri Setiawan
In flat-slab frames, which are typically designed as secondary seismic structures, the shear failure of the slab around the column (punching failure) is typically the governing failure mode which limits the deformation capacity and can potentially lead to ...
SPRINGER2022Steel Sheet Sheathed Cold-Formed Steel Framed In-line Wall Systems. I: Impact of Structural Detailing
The North American construction industry has seen substantial growth in the use of cold-formed steel (CFS) framing for midrise buildings in recent years. In seismic zones, CFS-framed buildings utilize shear walls to provide the primary lateral resistance t ...
ASCE-AMER SOC CIVIL ENGINEERS2022Spatio-temporal patterns of fluid-driven aseismic slip transients: implications to seismic swarms
Brice Tanguy Alphonse Lecampion, Alexis Alejandro Sáez Uribe
Seismic swarms are often interpreted to be driven by natural fluid pressurization in the Earth’s crust, when seismicity is observed to spread away from a common origin and follows approximately a square-root-of-time pattern of growth. On the other hand, a ...
EGU2022Seismic performance of structures incorporating seismic isolation with lead-rubber bearings
The emergence of new high-performance materials and equipment, as well as advancements in numerical calculation techniques, have allowed base isolation to take its place among the strategies used by engineers in earthquake resistant design. Despite the eno ...
2022Experimental plastic reactivation of pseudotachylyte‐filled shear zones
Marie Estelle Solange Violay, François Xavier Thibault Passelègue
Pseudotachylytes are fine‐grained fault rocks that solidify from melt that is produced in fault zones during earthquakes. Exposed sections of natural fault zones reveal evidence of post‐seismic plastic deformation (i.e. reactivation) of pseudotachylyte, wh ...
2021How does seismic anisotropy evolve as a function of mineralogical and textural changes across ductile shear zones? – an experimental and modelling approach
Henri Joseph François Gilles Leclère
Strain localization and the development of ductile shear zones in the middle and lower crust play major roles in lithosphere dynamics. Geophysical imaging of ductile shear zones is an issue for ore geology, for the understanding of the lithosphere rheology ...
2019Effect of Modeling Assumptions on the Earthquake-Induced Losses and Collapse Risk of Steel-Frame Buildings with Special Concentrically Braced Frames
Dimitrios Lignos, Seong-Hoon Hwang
This paper quantifies the collapse risk and earthquake-induced economic losses of steel-frame buildings with special concentrically braced frames designed in urban California. A probabilistic building-specific loss estimation methodology that can explicitl ...
Asce-Amer Soc Civil Engineers2017Experimental and Numerical Evaluation of Steel Columns for Performance-Based Seismic Assessment of Steel Moment Frames
Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady, Alexander Riley Hartloper
This paper summarizes the findings of a long term experimental program corroborated with detailed finite element simulations that investigated the hysteretic behavior of wide-flange columns in steel moment-resisting frames (MRFs) designed in highly seismic ...
2017Earthquake-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 ...
