329212 - ASCE/SEI 41-17: A First Look

Saturday, April 21
10:00 AM - 11:30 AM
Location: Ballroom C

Description: Significant changes to how seismic evaluations and retrofits will be carried out are based on the 2017 edition of ASCE/SEI 41 Seismic Evaluation and Retrofit of Existing Buildings. This session will highlight the most significant updates to the provisions including discussions on Basic Performance Objective for Existing Buildings, revised Tier 1 and Tier 2 procedures, significant nonlinear analysis provision changes, nonstructural provision changes, and changes to the criteria for steel and concrete columns. Design examples of the most often used provisions will be included.

Learning Objectives:
• Understand the updates to ASCE 41
• Recognize changes for Tier 1 and Tier 2 procedures
• Appreciate how coordination between material standards occurs with ASCE 41
• Learn from experts on specific design examples on typically used provisions

James C. Parker

Senior Principal
Simpson Gumpertz & Heger Inc.

James C. Parker, S.E. is a Senior Principal at Simpson Gumpertz & Heger (SGH). James has extensive experience in both structural engineering and building enclosure structures. His work ranges from new structural design, to investigation and retrofit of existing buildings, and design of high-performance building facade structures. With SGH since 1985, his exposure both to new construction design and to existing building investigation/evaluation enables Mr. Parker to bring creative solutions to the design process that reflect a realistic understanding of the performance of building and enclosure structures.

Mr. Parker has worked extensively internationally performing seismic assessments of structures in areas of significant seismic risk worldwide. He has worked to establish programs and priorities for seismic rehabilitation and risk mitigation, including development of building inventory and loss and vulnerability studies. He has inspected facilities, performed seismic analysis, and developed designs of seismic retrofitting for existing buildings. He has worked extensively as a voting member of the Seismic Rehabilitation Committee member for the American Society of Civil Engineers ASCE 31 and ASCE 41 which are state of the art standards for seismic evaluation and rehabilitation.

In addition, James is the author of the AISC Design Guide 22, Facade Attachments to Steel-Framed Buildings and has presented an AISC lecture series on the Guide. He frequently lectures and writes about topics regarding lessons learned on design projects, building information modeling, seismic design, and current issues within structural engineering.
