Sensitivity of Simulated Steel Column Instabilities to Plasticity Model Assumptions

Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Alexander Riley Hartloper

Current experimental studies on the seismic behavior of steel wide-flange columns under multi-axis cyclic loading reveal that these members, depending on their geometric characteristics, may be susceptible to axial shortening, out-of-plane deformations and ...

Concepts to minimize earthquake-induced column axial shortening in steel moment-resisting frames

Dimitrios Lignos, Hiroyuki Inamasu

Capacity-designed steel moment-resisting frames (MRFs) dissipate the seismic action through inelastic flexural yielding of protected zones located at the beam ends and the first story column bottom end. During low-probability of occurrence seismic events, ...

A-seismic fracture growth driven by fluid injection and remote nucleation of dynamic rupture in a weaker part of the fault

Brice Tanguy Alphonse Lecampion, Andreas Möri, Federico Ciardo

Induced (and triggered) seismicity following fluid injections at depth, is governed by pore pressure diffusion. Interestingly, recent studies yield unrealistically large values of diffusivity in order to explain the timing of the generated seismicity. We i ...

Capacity design principles for the ductile behaviour of conventional and high-performance steel structures under earthquake shaking

Dimitrios Lignos

Steel lateral load-resisting systems offer a variety of design solutions to ensure a ductile behaviour of a structure during a seismic event, thereby achieving a relatively low earthquake-induced collapse risk, if designed and detailed properly according t ...

Centre suisse de la construction métallique (SZS)2019

Rapid structural damage assessment methodologies are essential to properly allocate emergency response and minimize business interruption due to downtime in the aftermath of earthquakes. Within this context, data-driven algorithms supported by sensing capa ...

Developing earthquake scenarios for cities in areas with a moderate seismicity is a challenge due to the limited amount of available data, which is a source of large uncertainties. This concerns both the seismic hazard, for which only recordings for small ...

Lehrveranstaltungen in Baudynamik und Erdbebeningenieurwesen an der EPFL

Ian Smith, Pierino Lestuzzi, Katrin Beyer, Dimitrios Lignos

Baudynamik und Erdbebeningenieurwesen sind im Lehrplan des Bauingenieurwesens an der EPFL gut verankert. Baudynamik ist eine von nur fünf Pflichtveranstaltungen im Masterstudiengang und der Vorlesung muss daher von allen Studenten besucht und bestanden wer ...

Seismic performance of a steel moment frame subassembly tested from the onset of damage through collapse

Dimitrios Lignos

A series of seismic tests were conducted on a 1½-bay by 1½-story special steel moment-resisting frame subassembly from the onset of damage through incipient collapse. These tests were conducted using hybrid simulation with substructuring as a mean to demon ...

Wiley-Blackwell2016

This paper quantifies the lateral overstrength and the collapse risk of steel buildings with perimeter special moment frames (SMFs) designed in highly seismic regions in North America. State-of-the-art analytical models that consider the contributions of t ...

2015

This paper evaluates the effectiveness of single and multi-mode nonlinear static procedures (NSPs) as well as the FEMA P58 simplified approach versus rigorous nonlinear response history analyses (NRHA) for estimating seismic demands of steel special moment ...
