The Lefkandi-Toumba Building as a Timber-Framed Structure
Autor: Alexandra Coucouzeli, Allan McRobie, Igor Kavrakov
Publikováno v: EXARC Journal, Iss 2024/4 (2024)
The article demonstrates that the building or megaron on the Toumba hill at Lefkandi (Euboea), dating from c.950 BC, was a timber-framed structure, in contrast to the common view of it as a building with loadbearing walls. This raises the possibility

A Comparative Assessment of Aerodynamic Models for Buffeting and Flutter of Long-Span Bridges
Autor: Igor Kavrakov, Guido Morgenthal
Publikováno v: Engineering, Vol 3, Iss 6, Pp 823-838 (2017)
Wind-induced vibrations commonly represent the leading criterion in the design of long-span bridges. The aerodynamic forces in bridge aerodynamics are mainly based on the quasi-steady and linear unsteady theory. This paper aims to investigate differe

Physics-informed Gaussian process model for Euler-Bernoulli beam elements
Autor: Gledson Rodrigo Tondo, Sebastian Rau, Igor Kavrakov, Guido Morgenthal
Publikováno v: IABSE Symposium, Prague 2022: Challenges for Existing and Oncoming Structures.
A physics-informed machine learning model, in the form of a multi-output Gaussian process, is formulated using the Euler-Bernoulli beam equation. Given appropriate datasets, the model can be used to regress the analytical value of the structure’s b

Numerical investigation of the nonlinear interaction between the sinusoidal motion-induced and gust-induced forces acting on bridge decks
Autor: Samuel Tesfaye, Igor Kavrakov, Guido Morgenthal
With the increasing spans and complex deck shapes, aerodynamic nonlinearity becomes a crucial concern in the design of long-span bridges. This paper investigates the nonlinear interaction between the gust-induced and motion-induced forces acting on b

Determination of complex aerodynamic admittance of bridge decks under deterministic gusts using the Vortex Particle Method
Autor: Igor Kavrakov, Simone Omarini, Daniele Rocchi, Guido Morgenthal, Tommaso Argentini
Long-span bridges are prone to wind-induced vibrations. Therefore, a reliable representation of the aerodynamic forces acting on a bridge deck is of a major significance for the design of such structures. This paper presents a systematic study of the

Comparison Metrics for Time-histories: Application to Bridge Aerodynamics
Autor: Igor Kavrakov, Ahsan Kareem, Guido Morgenthal
Wind effects can be critical for the design of lifelines such as long-span bridges. The existence of a significant number of aerodynamic force models, used to assess the performance of bridges, poses an important question regarding their comparison a
