پاورپوینت بررسی کلی رفتار ديناميکی سازه ها Overview of Structural Dynamics

     As mentioned earlier, the primary objective of a structural dynamic analysis is the evaluation of the displacement  time histories of a given structure subjected to a given time varying loading. In most cases, an approximate analysis involving only a limited number of degrees of freedom will provide sufficient accuracy; thus, the problem can be reduced to the determination of the time histories of these selected displacement components.
    The mathematical expressions defining the dynamic displacements are called the equations of motion of the structure, and the solution of these equations of motion provides the required displacement time histories.
