Design of Thick Plate Double-Tee Connections for Seismic Applications
Publication: Practice Periodical on Structural Design and Construction
Volume 21, Issue 4
Abstract
Design of thick plate double-Tee connections is discussed and evaluated based on experimental data and analytical studies. This paper summarizes the results of an extensive experimental and analytical work aiming at widening the applicability of double-Tee connections needed for deep beams that meet the performance requirements for moment-resisting frames (MRFs) in seismic areas as specified in seismic provisions. New limit states controlling the strength and deformation capacities of the connections are presented. A detailed comprehensive design methodology and design examples of thick plate double-Tee connections are developed. The proposed design procedure includes all possible yielding mechanisms and failure modes that might occur in thick plate double-Tee connections and accounts for the maximum rotational capacity demand in the connection, as required for seismic analysis and design. The information presented in this paper can be used toward prequalification of thick plate double-Tee connections for use in MRFs in seismic areas.
