تحلیل و شبیه‌سازی دینامیکی سازه‌های تک درجه آزادی دارای جداساز لرزه‌ای با استفاده از نرم‌افزار متلب

One of the fundamental issues raised in the science of structural dynamics is the dynamic analysis of single-degree-of-freedom structures. For the dynamic analysis of this type of structures, common methods presented in the references are used. Although the dynamic analysis of such problems is not very complex, it helps a lot to understand the concept of dynamics of more complex structures with a higher number of degrees of freedom. In recent decades, the use of seismic isolators has had many applications in order to reduce the responses of a structure under earthquake excitation. A seismic isolator in a building causes certain changes in the dynamic characteristics of the building. These changes cause a decrease in the dynamic responses of the structure under earthquake excitation. Therefore, it can be said that the dynamic analysis of buildings with seismic isolators has a special place. Also, dynamic simulation of a structure under earthquake excitation can provide a proper insight and understanding of the behavior of the structure during an earthquake. Therefore, dynamic simulation of structures is of great importance to civil engineers. For the reasons stated, in this study, programs are presented for the dynamic analysis of single-degree-of-freedom structures with seismic isolators. These programs take the characteristics of the structure, the isolator, and the earthquake acceleration applied to the structure in the form of input files from the user and then perform dynamic analysis and dynamic simulation of the structure. It should be noted that important results of the dynamic analysis of the structure are also presented by the programs. Finally, the effect of the damping of the isolator system and the mass of the structure foundation on the response of the structure is examined.
