A Softening Constitutive Law and Gradient-Inelastic Fiber-Based Element for 3-Dimensional Frame Simulations Under Seismic Excitations
Steel frame structures are essential components of modern infrastructure. Understanding their behavior under seismic loading is critical for ensuring public safety and minimizing damage that occurs during earthquakes. To accurately predict the response of ...
EPFL2024Reuse of cut concrete slabs in new buildings for circular ultra-low-carbon floor designs
Corentin Jean Dominique Fivet, Célia Marine Küpfer, Numa Joy Bertola
The study explores an original idea that responds to the urgent need to reduce the detrimental environmental impacts of load-bearing floor construction in new buildings by reusing saw-cut reinforced concrete (RC) pieces salvaged from soon-to-be demolished ...
2024Proposed residual stress model for hot‐rolled wide flange steel cross sections
Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Andronikos Skiadopoulos
Residual stresses in hot-rolled wide flange steel cross sections may lead to premature yielding, accelerated corrosion and brittle fracture of steel members. The above phenomena lead to a loss of a steel member's stiffness and resistance under mechanical l ...
2023Dissipative Embedded Column Bases for Enhanced Seismic Performance of Steel Moment Resisting Frames
Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Hiroyuki Inamasu
This paper presents an innovative design concept for embedded column base (ECB) connections. The developed ECB connection achieves a non-degrading hysteretic response. In the proposed ECB connections, the dissipative zone is shifted into the embedded porti ...
EEME2023Geometric tolerances of welded connections with inelastic panel zones
Dimitrios Lignos, Andronikos Skiadopoulos, Ce Wen
Prequalified beam-to-column connections in steel moment resisting frames usually concentrate inelastic deformations in the steel beam ends. As such, nonlinear geo-metric instabilities (i.e., local buckling) may occur in these regions at modest lateral drif ...
