119. A prescriptive method for the design of new steel moment frame structures with supplemental damping
This paper presents a prescriptive method for the design of new steel moment frame structures with supplemental damping using fluid viscous dampers (FVDs). The prescriptive method uses Modal Response Spectrum Analysis (MRSA) instead of Nonlinear Response History Analysis (NLRHA) as the basis for evaluation. Additionally, the procedure decouples the design of the moment frame from the damper frame, reducing design iterations. This makes the use of FVDs in new buildings easier to evaluate at schematic level design and significantly reduces the effort for full design. The procedure produces a 25% viscous damping ratio at the Design Earthquake (10% probability of exceedance in 50 years) and requires the use of nonlinear dampers with a damping exponent, alpha of 0.4.
118. A review of the state of practice for fluid viscous damper applications in North America and New Zealand
This paper will explore best practices collected through involvement with hundreds of damper projects worldwide. Lessons learned through the entire damper design process, from schematic level decisions through construction implementation, will be explored for both steel and concrete buildings. The purpose of this paper is to broaden readers’ understanding of FVD applications in the North American and New Zealand markets with the aim of reducing barriers and to demonstrate the ease of design and implementation of damped solutions.
117. Prescriptive Design of Damped Moment Frames: Simplifying building design with fluid viscous dampers by using an ICC-approved prescriptive method
Taylor Devices’ dampers are featured on the cover photo of the November issue of STRUCTURE magazine, along with an article about the Taylor Damped Moment Frame™. Written by Nathan Canney, Ph.D., P.E., Konrad Eriksen, and Alan Klembczyk, the article covers everything from an introduction to dampers to how the TDMF™ compares to other LFRS in building performance, loss and recovery time at the DE level.
