  1. Tall Buildings Initiative • 3 year initiative to advance design of tall buildings • Main participants • PEER, SCEC, USGS, FEMA, CSMIP, Pankow Foundation, SFDBI, LADBS, OES, CSSC, ATC, LATBSDC, SEAOC, SEAONC • Project Management Committee (T-PAC) • J. Moehle, Y. Bozorgnia • N. Abrahamson, M. Lew, P. Somerville • R. Hamburger, H. Krawinkler, M. Moore (SEAOC), F. Naeim • R. Lui

  2. Collapse safety (2500 years) Performance Objectives • Core group: W. Holmes, C. Kircher, L. Kornfield, B. Petak, N. Youssef • Stakeholder views

  3. Ground motion simulation, review, and selection and scaling guidelines • Simulation: P. Somerville, B. Aagaard, N. Collins, R. Graves • Review: F. Naeim, Y. Bozorgnia, N. Abrahamson, B. Chiou, CB Crouse, D. Dreger, Y. Moriwaki, Y. Zeng • Guidelines: Y. Bozorgnia, N. Luco, F. Naeim, J. Hooper, N. Abrahamson, J. Maffei

  4. Input ground motions for tall buildings with subterranean levels • Core Group: J. Stewart, C.B. Crouse, M. Lew, A. Mikami, F. Ostadan, E. Taciroglu • Report available for review

  5. Guidelines for Modeling and Acceptance Criteria (ATC 72) • Core group – J. Malley, G. Deierlein, H. Krawinkler, J. Maffei, M. Pourzanjani and J. Wallace • Approach: Workshop identified key issues, assignments to experts to develop principles, procedures, and values. • Key issues: • Good practices in nonlinear dynamic analysis (H. Krawinkler, G. Deierlein, J. Heintz) • Podium and basement modeling and performance characterization (J. Maffei, J. Malley) • Wall modeling and performance characterization (J. Wallace, M. Pourzanjani)

  6. Building Pilot Studies • Core group: J. Moehle, S. Mahin, J. Hooper, T. Yang, C. McQuoid, Tea Visnic • Approach • Representative building models • Variations in model parameters • 100s of ground motions in various M, r , etc. bins • Ground motion selection and scaling tests

  7. Performance of TBI-designed buildings Sa (T = 3 sec, z = 5%)

  8. Guidelines for performance-based seismic design of tall buildings October 2010
