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 ...

Due to safety issues, many of the existing reinforced concrete structures in Cyprus, built 50 years ago, require immediate retrofitting. In general, a great number of structures have issues with reinforcement corrosion ...

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 ...

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 ...

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 ...

In the decades of 1950s, 1960s, 1970s, and 1980s most of the buildings in Cyprus, an island in the Mediterranean Sea which is located to a high seismicity region, were designed without seismic design criteria and ...

This paper forms a literature survey on lumped and distributed parameter, linear, viscously damped, dynamic systems, possessing non-classical modes.

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 ...

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 ...

Prelemenary free hull girder vibration study of offshore patrol vessel of Hellenic Navy

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 ...

The research aims to investigate the existing design standards KANEPE (2017) [1] and EN 1998-3 (2005) [2] regarding the seismic assessment of existing reinforced concrete structures through a real case study. Also, the ...

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 ...

Tuned Mass Dampers (TMDs) is an effective way for mitigating vibrations and sways in engi neering structures under lateral actions, such as strong winds. Thus, TMDs can enhance safe ty and reduce design structural demands. ...

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 ...

Several decades of research and development placed new tools in the hands of engineers, builders, supervisors, surveyors, contractors and all people associated with the construction industry. In this paper, we are referring ...

Δύο δεκαετίες έρευνας οδήγησαν στην γέννηση ενός νέου εργαλείου στα χέρια των μηχανικών. Ενός προγράμματος, δηλαδή, ηλεκτρονικού υπολογιστή που χρησιμοποιεί τις διαθέσιμες σύγχρονες τεχνολογίες, και που δίνει την δυνατότητα ...

Η παρούσα διπλωματική εργασία έχει θέμα την διερεύνηση της αντισεισμικής συμπεριφοράς ενός οκταόροφου κτηρίου μέσης κατηγορίας πλαστημότητας, αναπτύσσοντας ταυτόχρονα ένα μοντέλο ανάλυσης της κατασκευής από οπλισμένο ...
