Abstract: According to one embodiment, the energy dissipation of a structural element is increased by inserting one or more resisting elements into the structural element at any time during or after construction of the structural element. The continuous resisting elements are rigidly attached to the structural at one end and connected to the structural element by and through a damping material over at least a portion of its length. When a dynamic force is applied to the structural elements, such as may result from wind or earthquakes, there will be a strain in the structure, in a direction parallel with the longitudinal direction of the resisting elements. In this way, the forces and deformations within the structure will result in a relative motion between the structural element and resisting element, a substantial portion of which is ultimately transmitted by and through the damping material layer.
