Outrigger system for interconnecting three dimensional multi-stories buildings

In tall buildings design, lateral loads induced by wind or earthquake forces are often resisted by an outrigger system. This system is often chosen as its function by tying the structural components together to provide sufficient lateral stiffness to the structure and control the excessive drift due...
