Coextrusion : a feasible method to manufacture negative stiffness inclusionsHook, Daniel Taylor 15 November 2013 (has links)
This work demonstrates the effectiveness of coextrusion as a method to manufacture negative stiffness inclusions for use in vibrational damping applications. The theory and mechanics of negative stiffness and coextrusion are introduced and the process of creating and extruding a feed rod with negative stiffness architecture explained. Coextrusion is shown to be a viable method to create negative stiffness inclusions / text

Ισοδύναμη ιξώδης απόσβεση για ανελαστική σεισμική ανάλυση μεταλλικών πλαισίων μέσω ελαστικής δυναμικής φασματικής ανάλυσηςΚωνσταντακόπουλος, Ιωάννης 30 April 2014 (has links)
Στην παρούσα διατριβή παρουσιάζονται τα αποτελέσματα μιας εκτεταμένης διερεύνησης της ανελαστικής συμπεριφοράς επίπεδων μεταλλικών καμπτικών πλαισίων. Η διερεύνηση περιλαμβάνει 36 συνολικά πλαίσια με διαφορετικές ιδιότητες, όπως αριθμός ανοιγμάτων και ορόφων τα οποία τα οποία αναλύονται με βηματικές δυναμικές ανελαστικές αναλύσεις για 20 σεισμικές κινήσεις προκειμένου να καθοριστεί η απόκριση τους (μετακινήσεις και τέμνουσα βάσης) στα συγκεκριμένα ανελαστικά επίπεδα βλάβης, που καθορίζουν οι αντισεισμικοί κανονισμοί παγκοσμίως. Έπειτα υπολογίζεται ο κατάλληλος συντελεστής ιξώδους απόσβεσης ίδιος για όλες τις πρώτες ιδιομορφές ώστε με χρήση ελαστικής φασματικής ανάλυσης των πλαισίων να δίνει τα ίδια αποτελέσματα σε επίπεδο δυνάμεων με αυτά της ανελαστικής. Αυτό απαιτεί την κατασκευή φασμάτων σχεδιασμού με υψηλές τιμές ιξώδους απόσβεση. Τέλος παρουσιάζονται εμπειρικοί τύποι υπολογισμού αυτού του συντελεστή απόσβεσης για κάθε κτήριο και κάθε επίπεδο επιτελεστικότητας προς διευκόλυνση του μηχανικού. / This thesis presents the results of an extensive investigation of the nonlinear behavior of steel bending frames. The investigation includes a number of 36 frames with different properties, such as number of openings and floors which are analyzed by step by step dynamic inelastic analysis for 20 seismic movements in order to determine their response (movement and base shear) in particular inelastic damage levels, which determine the Seismic Codes. Furthermore, the appropriate damping rate, which is the same for all the first modes, was calculated using spectral analysis of elastic frames with the purpose of giving the same results at the level of forces are inelastic . This requires the construction of design spectra with high damping. Finally it is presented empirical formulas of calculating the daming ratio for each building and each performance level to facilitate engineers.
