A shearwall is disclosed for use in lightweight or other constructions to transmit lateral shear forces and dissipate energy on the construction. In examples, the shearwall includes a central panel formed of wood, and side plates formed of steel. The side plates may be affixed at lower corners of first and second opposed surfaces of the central panel. Each side plate may include a fastening plate for affixing the side plate to the central panel, and a restraint plate which fits within a reduced area section of the central panel between the first and second surfaces.
