The multi-threaded structure of active region coronal loops was deduced from past spectroscopic observations. Recent high resolution observations by TRACE and Hinode provide direct evidence that active region loops consist of multiple magnetic threads filled with plasma with higher density than neighboring loop material. High resolution observations of loops near a flare site suggest that the threads are twisted, and the magnetic field is not force-free. To better understand these observations I developed 3D MHD model of twisted multi-threaded loop oscillations. The twist is induced by applying rotating velocity field at the foot-point of the initially parallel set of threads. The oscillations of the twisted loops are excited by a fast magnetosonic pulse. The evolution and the damping of the fast magnetosonic wave excited in the twisted multi-threaded loop is compared to the wave in single threaded loop, and to parallel threaded loop. The results of the study show the effect of the twist and internal loop structure on the damping of the waves. *Visiting Associate Professor, Tel Aviv University
