Seismic Design and Analytical Modeling of Posttensioned Hybrid Coupled Wall Subassemblages

Abstract

This paper uses the experimental results presented in a companion paper to develop a seismic design approach for unbonded posttensioned hybrid coupled wall subassemblages. The test results are also used to verify and refine analytical models for the subassemblages. The proposed design approach includes guidelines for the selection of the coupling beam cross-section and the posttensioning steel area, as well as the design of the top and seat angles, their connections, and the design of the concrete wall contact regions.
