Seismic Assessment and Retrofit of Pre-Northridge High Rise Steel Moment Resisting Frame Buildings with Bilinear Oil Dampers

Autor: Sarven Akcelyan, Dimitrios G. Lignos

Publikováno v: Buildings, Vol 13, Iss 1, p 139 (2023)

This paper presents quantitative information on the effectiveness of seismic retrofit solutions using bilinear oil dampers for seismically deficient existing tall steel buildings. For this purpose, a benchmark 40-story steel space moment-resisting fr

Fragility Assessment of Beam-Slab Connections for Informing Earthquake-Induced Repairs in Composite-Steel Moment Resisting Frames

Autor: Hammad El Jisr, Dimitrios G. Lignos

Publikováno v: Frontiers in Built Environment, Vol 7 (2021)

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 bet

EaRL—Software for Earthquake Risk, Loss and Lifecycle Analysis

Autor: Ahmed Elkady, Dimitrios G. Lignos

Publikováno v: SoftwareX, Vol 12, Iss , Pp 100607- (2020)

Performance-based earthquake engineering (PBEE) has become an increasingly popular framework to design, retrofit and manage structures. This probabilistic framework integrates data from the seismic hazard, structural response, damage fragility and da

The automated collapse data constructor technique and the data‐driven methodology for seismic collapse risk assessment

Autor: Nenad Bijelić, Dimitrios G. Lignos, Alexandre Alahi

Publikováno v: Earthquake Engineering & Structural Dynamics. 52:2452-2479

Majority of the past research on application of machine learning (ML) in earthquake engineering focused on contrasting the predictive performance of different ML algorithms. In contrast, the emphasis of this paper is on the use of data to boost the p

Seismic design and performance of steel concentrically braced frame buildings with dissipative floor connectors

Autor: Martina Paronesso, Dimitrios G. Lignos

Publikováno v: Earthquake Engineering & Structural Dynamics. 51:3505-3525

This paper explores the use of sliding friction dampers (SFDs) as dissipative floor connectors to mitigate higher mode effects and earthquake-induced absolute acceleration demands on steel concentrically braced frame (CBF) buildings. The dampers conn

A Displacement-Based Fiber Element to Simulate Interactive Lateral Torsional and Local Buckling in Steel Members

Autor: Arka Maity, Amit Kanvinde, Diego I. Heredia Rosa, Albano de Castro e Sousa, Dimitrios G. Lignos

Publikováno v: Journal of Structural Engineering. 149

Collapse in steel structures is often controlled by loss of load carrying capacity of steel columns due to interactive buckling, which involves interactions between local and global (i.e., lateral and lateral torsional) buckling. Commonly used concen
