Texto completobased seismic isolator type on the basis of the idea that the damping of a conventional annular elastomeric bearing (EB) can be increased by filling its central core with small diameter steel balls, which dissipate energy via friction inside the confined hole of the bearing during their movements under horizontal loads. The proposed bearing type is called &ldquo
Ball Rubber Bearing (BRB)&rdquo
. A large set of BRBs with different geometrical and material properties are manufactured and tested under reversed cyclic horizontal loading at different vertical compressive load levels. Effect of supplementary confinement in the central hole of the bearing to performance of BRB is studied by performing some additional tests. Test results are used to develop design equations for BRB. A detailed non-linear finite element model is developed to verify the test results. The proposed analytical model is determined to simulate the structural hysteretic behaviour of the bearings. In design of BRBs, the proposed design guideline can be used in conjunction with the proposed non-linear finite element analysis. Extensive test results indicate that steel balls do not only increase the energy dissipation capacity of the elastomeric bearing (EB) but also increase its horizontal and vertical stiffness. It is also observed that the energy dissipation capacity of a BRB does not degrade as the number of loading cycles increases, which indicates remarkably reliable seismic performance.

The implementation of various structural control systems, such as passive, semi-active or active is not a new concept. They are incorporated in structures to increase the performance under seismic and/or wind loading either by adding stiffness or inducing counteracting forces which dissipate energy in various ways. In order to efficiently dissipate the seismic energy with existing schemes, large structural displacements are required. However, structures that are most vulnerable to earthquakes such as low-rise relatively stiff buildings, cannot experience significant displacements. Therein lies the challenge the author attempts to address by proposing a structural scheme which can be applied to low-rise concrete buildings to efficiently dissipate seismic energy and at the same time to considerably decrease the forces in the structural members for a given seismic excitation. In this thesis the design of this new structural scheme is described and a case study is performed in order to demonstrate its effectiveness and applicability.

Texto completoThe thesis investigates the seismic reliability of isolated structures with FPBs (Friction Pendulum Bearings) towards failure due to high vertical component excitation and friction coefficient variations. In the end, it has been studied the influence of the uncertainty of the input excitation on the vulnerability of complex structures such as viaducts in the case of different seismic isolation strategies application. The last seismic events (Christchurch 2011, L’Aquila 2009) have highlighted lacks in the actual design philosophies (PBD) due to the high structural damage experimented by structures. The Passive Control Technique of seismic response allows high structural performances respect to the one of fixed base structures, in this way making sustainable the repairing costs of structures in the case of medium high intensity seismic event. After introducing a rich bibliography on matemathical theory of base isolated structures, with some remarks on the state space formulation which allow to carry out modal analysis of non classically damped structures such as the one object of the study, on the mechanical and dynamical behavior of Friction Pendulum System device and on the current Technical Code in Italy (NTC08), it has been introduced the theme to be investigated. Being the FPS behavior related to the friction force, the seismic response can be affected by particular seismic event as near fault event characterized by high vertical component intensity of seismic excitation. Moreover the degradation of the sliding interface due to velocity, pressure and temperature variations can influence the seismic response of the device. To the scope of investigating the collapse phenomenon of the device, non linear dynamic analysis have been carried out through deterministic parametric methods with different near fault input excitations, on two different systems: the first described by a rigid superstructure and isolation system described by the Nagarajaiah model (1990), the second representative of a benchmark r.c. building of four levels (Almazan 2003). The subsequent stochastic analysis carried out by means of the use of Montecarlo simulation, taking advantage of the inversion method, on a system described by rigid superstructure and isolation system described by a rigid-plastic behavior with hardening, have highlighted the relation between the stochastic response and the uncertainty of the friction coefficient in the case of sinusoidal excitation. Finally, it has been investigated the vulnerability of bridge structures in different isolation system design configurations by using fragility analysis, carried out taking advantage of the Multi Stripes method (Baker 2014). Results show the probability of exceedance of the limit state considered variations taking into account the uncertainty of the input excitation. [edited by author]
Il lavoro di tesi ha indagato l’affidabilità sismica delle strutture isolate mediante dispositivi FPBs (Friction Pendulum Bearings) nei confronti dei fenomeni dello scalottamento e delle variazioni del coefficiente d’attrito che caratterizza l’interfaccia di scorrimento del dispositivo. In ultima analisi, è stata indagata l’influenza dell’aleatorietà dell’input in ingresso sulla vulnerabilità di strutture complesse quali viadotti nel caso di applicazione di differenti strategie di isolamento. Gli ultimi eventi sismici (Christchurch 2011, L’Aquila 2009) hanno evidenziato carenze nelle filosofie prestazionali attuali (PBD) a causa dell’elevato danneggiamento agli elementi strutturali sperimentato dalle costruzioni. Le tecniche di controllo passivo della risposta sismica consentono elevate prestazioni in termini di performance strutturali rispetto a quelle a base fissa, in tal modo rendendo sostenibili i costi di riparazione delle costruzioni in caso di eventi sismici di medio alta intensità. Dopo una ricca bibliografia sulla teoria matematica alla base delle strutture isolate, con cenni alla formulazione nello spazio degli stati che consente l’analisi modale di strutture non classicamente smorzate, sul comportamento meccanico e dinamico del dispositivo Friction Pendulum System e sulle attuali Norme Vigenti in Italia (NTC08), si è introdotta la problematica oggetto di studio. Essendo il comportamento del dispositivo FPS dipendente dalla forza d’attrito, la risposta sismica può essere affetta da particolari eventi sismici di tipo near fault caratterizzati da componenti verticali dell’eccitazione sismica di elevata intensità. Inoltre l’usura della superficie di scorrimento dovuta a variazioni di velocità, pressione e temperatura può influenzare la risposta sismica del dispositivo. Al fine di indagare il fenomeno dello scalottamento del dispositivo sono state condotte analisi dinamiche non lineari mediante metodologie deterministiche parametriche con differenti eccitazioni in ingresso di tipo near fault, su un sistema descritto da una sovrastruttura rigida e sistema di isolamento descritto dal modello di Nagarajaiah (1990), e su un sistema rappresentativo di un edificio benchmark in c.a. a 4 livelli (Almazan 2003). Inoltre, le successive analisi stocastiche condotte mediante l’utilizzo della simulazione Montecarlo, sfruttando il metodo dell’inversione, su un sistema descritto da sovrastruttura rigida e sistema di isolamento descritto da una legge attritiva rigido plastica con incrudimento, hanno messo in evidenza la dipendenza della risposta stocastica dall’aleatorietà del coefficiente d’attrito nei confronti di eccitazioni sinusoidali. Infine è stata indagata la vulnerabilità di strutture da ponte in differenti configurazioni di progetto del sistema di isolamento mediante analisi di fragilità condotte sfruttando il metodo Multi Stripes (Baker 2014). Esse mostrano le variazioni nella probabilità di superamento degli stati limite in considerazione dell’aleatorietà dell’input in ingresso. [a cura dell'autore]

Texto completowhereas, due to the increased stiffness of the system, at high frequencies dry friction damper has a mitigating effect on performance. In order to overcome this problem, original system parameters are modified. In the modified system a softer mount that increase vibration isolation performance at high frequencies
but, which might cause excessive static deflection due to reduced stiffness of the system is used. On the other hand, addition of dry friction damping prevents excessive static deflections due to the increased stiffness effect and also increases the performance at high frequencies due to the soft mount. Final results showed that vibration isolation performance at low frequencies increases considerably while vibration isolation performance at high frequency is similar and even slightly better than the original system with addition of dry friction damping.
