heal.abstract Σκοπός της εργασίας είναι να αναδείξει τη συμβολή των κραμάτων αλουμινίου με μνήμη σχήματος στην αντισεισμική προστασία των κατασκευών. Ως εκ τούτου, γίνεται δυναμική ανάλυση μονοβάθμιων ταλαντωτών και επίπεδων πλαισιωτών φορέων που στη μία περίπτωση αποτελούνται αποκλειστικά από δομικό χάλυβα και στην άλλη γίνεται χρήση και κραμάτων αλουμινίου με μνήμη σχήματος. el
heal.abstract The aim of the present diploma thesis is the research and study of the behavior of shape memory alloys in civil engineering applications. These materials also known as “smart” materials are used in various domains of contemporary society as they are characterized by two main properties. One of them is the “shape memory effect” and the other the “superelasticity”. The first chapter refers to a complete definition of those materials and a brief description of the properties. Furthermore, their contribution and use in various applications of civil engineering is analyzed. The second chapter contains complete description of crystalize structure of shape memory alloys which at the same time is responsible for their properties. Afterwards an analytical description of these properties is given so that they can be understandable and defined. The third chapter is mainly mathematical and deals with models which simulate the behavior of superelasticity which have the shape memory alloys in recharging. Model simulators referring to the superelasticity of the “smart” materials are presented as well as the two lined kinetic motion model with which they are compared in the following chapters. The fourth chapter studies the behavior of a single-degree of freedom oscillator under dynamic loads. Hypothetically the material of the oscillator is made either by structural steel or by “smart” materials and through dynamic analysis that take place, we come to conclusions for the use and contribution of shape memory alloys in the civil engineer’s construction. The fifth chapter contributes to the integration of this survey by presenting the “static pushover” and dynamic analysis of two dimensions frameworks. These frameworks are single floor, two floor and six floor buildings consisting of diagonal x-shaped stiffness links. For the materials of the x-shaped links it is supposed that they consist in one of the occasions of common structural steel and in another occasion of material nitinols (smart material). Various suppositions also take place about their cross-sectional area. Lastly, the sixth chapter is the chapter of the completion of the present diploma thesis noting the conclusions from the analysis which took place in various constructions that were presented and analyzed in previous chapters. en
