Abstract

The objective of this paper is to evaluate the impact of applying the ASCE 41-17 performance-based design provisions on a 2-story case study building previously design and tested during the CFS-NEES research project. The latest version of the American Society of Civil Engineers Standard 41 (ASCE 41-17) incorporates new provisions for the assessment of cold-formed steel (CFS) systems. These provisions include component acceptance criteria derived from a database of available experimental data. Though the new set of criteria was rigorously devel-oped, there was limited understanding of how this criteria would score a newly-designed CFS building using the standard approaches employed by engineers (e.g., using ASCE 7-16 to determine loads and AISI S100 and AISI S400 to de-termine capacities). Given that the vast majority of CFS buildings are designed using linear procedures, particular interest is given to comparing the linear proce-dures for new design versus ASCE 41 assessment (i.e., existing building as-sessment). Additionally, ASCE 41-17 can be used as an alternative approach to new building design, thus providing additional motivation for this comparison. Findings show that, though the 2-story building withstood shake table tests with intensities greater than the maximum considered earthquake, the results of an ASCE 41 assessment indicate the building's shear walls are deficient. This high-lights the disconnect between ASCE 41 and new building design. To resolve this disconnect, practical methodologies for accounting for system overstrength are suggested for consideration in future editions of ASCE 41
