Analytical Method to Determine the Elastic In-Plane Behavior of Pretopped, Precast Concrete Double-Tee Diaphragms with Discrete Connections

Observed behavior of parking structures, both during seismic events and in subsequent research, indicates that the in-plane behavior of precast concrete double-tee diaphragms may contribute to development of large displacements and affect the structure's seismic performance. The aims of this study were to develop a rigorous analytical basis for practical modeling and determination of elastic in-plane behavior and force distribution among connectors. The elastic in-plane behavior of 10 diaphragm configurations with 4 types of connectors, 2 different connector spacings, and 2 different amounts of chord-member steel was analyzed and compared with that of a monolithic concrete diaphragm. The modeling concepts developed were related to overall connection behavior in the connection zone. They can also be applied to other discretely joined precast concrete structures that exhibit elastic or inelastic behavior mainly in the connection zone.
