The Analysis of the Response of RC Buildings through Virtual Reality Techniques
Bellos, John (2010)Στο άρθρο παρουσιάζεται το σύγχρονο λογισμικό της εικονικής πραγματικότητας που έχουμε αναπτύξει, σαν εργαλείο αντισεισμικού σχεδιασμού κτηρίων από οπλισμένο σκυρόδεμα. Θα θέλαμε να επισημάνουμε ότι οποιαδήποτε λεκτική ...

Complete analytical solution of linear soil pressure on rigid spread rectangular footings
Bellos, John (2015)In this paper the complete analytical solution concerning the linear soil pressure on rigid spread rectangular footings is formulated. All five distinct regions on the eccentricity map are related to five possible types ...

Controlling flexible structures with second order actuator dynamics
Inman, Daniel; Umland, Jeffrey W.; Bellos, John (1989)The control of flexible structures for those systems with actuators that are modeled by second order dynamics is examined. Two modeling approaches are investigated. First a stability and performance analysis is performed ...

Frequency Response of Nonproportionally Damped, Lumped Parameter, Linear Dynamic Systems
Bellos, John; Inman, Daniel (Technical Committee on Vibration and Sound, 1990)The frequency response of nonproportionally (or nonclassically or non-Raleigh) damped linear lumped mass systems is discussed here. The exact method, via Laplace transforms, is presented and the practical difficulties ...

Literature Review
Bellos, John; Inman, Daniel (Shock and Vibration Information Center, 1989)This paper forms a literature survey on lumped and distributed parameter, linear, viscously damped, dynamic systems, possessing non-classical modes.

Lumped Systems with Nonproportional Damping
Bellos, John; Inman, Daniel (1988)The time domain response of non-proportionally damped or non-classical normal mode or non-Rayleigh linear lumped parameter systems, as otherwise called, is derived. Modal analysis is used to transform the governing equations ...

Nature of coupling in nonconservative lumped parameter systems
Bellos, John; Inman, Daniel (American Institute of Aeronautics and Astrnautics, 1989)Although the response of undamped or at least proportionally damped linear systems can be determined easily by modal analysis, the prediction of the response of nonproportionally damped linear systems requires either more ...

Numerical aspects of incremental dynamic analysis for the retrofitting of existing industrial steel building utilizing SSCD dampers
Bellos, John; Bakas, Nikolaos; Castiglioni, Carlo (2017)In this work, the nonlinear analysis of an existing industrial steel structure (Sodium building), and its retrofitting using SSCD dampers is demonstrated. Specific numerical complications of incremental dynamic (IDA) and ...

Simplified Numerical Modeling of Elevated Silos for Nonlinear Dynamic Analysis
Castiglioni, Carlo Andrea; Kanyilmaz, Alper; Bellos, John (2015)Silos are industrial facilities used for storing a huge range of different materials. They should be designed to resist several loading conditions, and their seismic behaviour, which strongly depends on the geometrical and ...

Torsional design criteria in building codes and comparison with more accurate modeling using structural optimization tools
Bellos, John; Bakas, Nikolaos (4th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering, 2013)It is widely accepted that seismic design philosophies do not follow the efficiency of seismic analysis methods is quite remarkable. Torsionally unbalanced structures, is a common field where any of the proposed design ...
