The evaluated building is composed of 44 floors (39 floors on the ground, 5 underground) and is designed as 180 m high multi-story reinforced concrete structure. The lateral resisting system consists of reinforced concrete shear walls and moment frames.
The client has requested the building’s performance be evaluated in terms of post-earthquake sustainability and confirmation of business continuity. The most serious post-earthquake problems experienced in high rise buildings can be summarized as facade damages restricting the building usage, shutdown of vertical transportation resulting in direct business interruption and plumbing damages preventing the water supply.
The evaluation was carried out per USRC* (United States Resiliency Council) Rating System’s Safety, Damage and Recovery criteria.
