Seismic anchor system, apparatus, and structure including same

A structure comprising:

• a vertical wall;
• a concrete bed formed beneath the wall and extending beyond the wall;
• and
• a seismic anchor system for protecting the structure from potentially damaging ground movement and comprising a plurality of seismic anchors attached to the wall, each seismic anchor comprising:
• a main elongated member attached to the wall, the main elongated member having a first tensile strength;
• a secondary elongated member attached to the main elongated member, the secondary elongated member having a second tensile strength lower than the first tensile strength;
• and
• an anchor embedded in the concrete bed and including an anchor body attached to the secondary elongated member and a moveable stop member attached to the main elongated member, the moveable stop member allowed to move relative to the anchor body such that in a first mode force is applied to the anchor body through the secondary elongated member, and in a second mode in which the secondary elongated member has yielded, force is applied to the anchor body through the main elongated member and the moveable stop member.
