Tall Buildings Initiative (TBI)

 Purpose

 Develop design criteria and guidance for the seismic

design and review of tall buildings in high seismicity regions

 Tasks

 Develop consensus on performance objectives  Ground motion selection and scaling  Soil-foundation-structure interaction modeling  Benchmark studies of building dynamic response  Model building designs  Case studies: comparison of seismic performances  Development of performance-based design Guidelines  Modeling and acceptance criteria (ATC-72)
