Tall Buildings Initiative Task 7 - Guidelines on modeling and acceptance values
Task description – Develop practical guidance for nonlinear modeling of tall buildings in reinforced concrete (priority), steel, and composite construction. Conduct workshop to identify critical issues in tall buildings modeling and acceptance values, rather than covering the entire field. Identify researcher/practitioner teams to review the literature and conducted limited analyses to identify appropriate procedures. Methodology and findings to be documented in final report. Include recommendations for stiffness, strength, deformation capacity, hysteretic models, and implementation in software for nonlinear dynamic analysis. Provide guidance on appropriate use of overstrength parameters, capacity reduction parameters, etc. for capacity design. Work with experienced consultants to ensure focus on key components and systems that affect earthquake response and design, including modeling of podium force transfer. As appropriate, conduct analyses to validate procedures.
Lead investigator – James Malley
Team members – Greg Deierlein, Helmut Krawinkler, Joe Maffei, Mehran Pourzanjani, John Wallace, and others as needed.
