2017 TBI Guidelines Version 2.01 Now Available
PEER has just published Report No. 2017/06 titled: “Guidelines for Performance-Based Seismic Design of Tall Buildings,” Version 2.0, prepared by a TBI Working Group led by co-chairs Ron Hamburger and Jack Moehle: Jack Baker, Jonathan Bray, C.B. Crouse, Greg Deierlein, John Hooper, Marshall Lew, Joe Maffei, Stephen Mahin, James Malley, Farzad Naeim, Jonathan Stewart, John Wallace.
In the time since the publication of the 2010 Guidelines, the profession has gained substantial experience in application of performance-based techniques to design buildings around the world, and, in particular, the western United States.
This second edition addresses lessons learned in application of the first edition on many projects and the conditions, knowledge, and state-of-practice that presently exist.
2010 TBI Guidelines
The turn of the last century saw a surge in the construction of high-rise buildings. The surge created a demand for performance-based approaches to enable construction using new framing systems rising to heights outside the range of building code prescriptive provisions. The Pacific Earthquake Engineering Research Center (PEER) responded to this need by leading an initiative to develop design criteria that will ensure safe and usable tall buildings following future earthquakes. Download the primary product of this initiative: Guidelines for Performance-Based Seismic Design of Tall Buildings.
Collectively known as the Tall Buildings Initiative, this project involves the Applied Technology Council, Federal Emergency Management Agency, Los Angeles Department of Building and Safety, Los Angeles Tall Buildings Structural Design Council, California Seismic Safety Commission, San Francisco Department of Building Inspection, Southern California Earthquake Center, Structural Engineers Association of California, U.S. Geological Survey, PEER, and several practicing professionals.
The initiative funded a range of projects. Specific tasks for this initiative are:
- Task 1 – Establish the Tall Buildings Project Advisory Committee
- Task 2 – Develop consensus on performance objectives
- Task 3 – Baseline assessment of dynamic response characteristics of tall buildings
- Task 4 – Synthetically generated ground motions
- Task 5 – Review and validation of synthetically generated ground motions
- Task 6 – Guidelines on selection and modification of ground motions
- Task 7 – Guidelines on modeling and acceptance values
- Task 8 – Input ground motions for tall buildings with subterranean levels
- Task 9 – Presentations at conferences, workshops, seminars
- Task 10 – Performance-based seismic design guidelines for tall buildings
- Task 11 – Instrumentation (under development)
- Task 12 – Quantification of seismic performance levels of tall buildings
The later tasks will synthesize results of the earlier tasks to develop a framework for seismic design of tall buildings, summarized in a final Guidelines document containing principles and specific criteria for tall building seismic design. The document is intended to support ongoing guidelines and code-writing activities of collaborating organizations, as well as being a stand-alone reference for designers of high-rise buildings.
The initiative is guided by a Project Advisory Committee comprising:
Norm Abrahamson, Yousef Bozorgnia, Ron Hamburger, Helmut Krawinkler, Marshall Lew, Ray Lui, Jack Moehle, Nic Rodriguez , Farzad Naeim, and Paul Somerville.
Broader community engagement will be achieved through a series of regular workshops and other outreach activities.
