Seismic Design Methodology Document for Precast Concrete Diaphragms

Abstract

The design procedure in PART 1 is part of a new seismic design methodology for precast concrete diaphragms. The design methodology and procedure are the product of a large multi-university research project initiated and guided by the Precast/Prestressed Concrete Institute (PCI) and co-funded by PCI, the National Science Foundation (NSF) and the Charles Pankow Foundation (CPF), termed the Diaphragm Seismic Design Methodology (DSDM) project.

Diaphragm Seismic Design

“…Aspects of the research included subassembly tests of diaphragm connectors to establish connector performance; 4,5 a three-story, half-scale precast concrete structure subjected to 16 significant-input ground motions; 6 and detailed finite-element modeling using Ansys. 3 The overall key outcomes of the research 3 included the following:…”
