Abstract

This paper provides guidance for determining seismic design force level for topped precast concrete diaphragms. This has been a controversial topic ever since ASCE/SEI 7-16, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, introduced a section titled “Alternative Design Provisions for Diaphragms” and mandated its use for precast concrete diaphragms in buildings assigned to seismic design category C, D, E, or F.
