Performance-Based Capacity Design of Steel Plate Shear Walls. II: Design Provisions

Abstract

This is Part II of two companion papers on performance-based capacity design of steel plate shear walls. These papers aim to provide a holistic and sound basis for capacity design of steel plate shear walls to any of three explicit performance levels (ductile, moderately ductile, and limited-ductility), with emphasis on design requirements for applications involving lower ductility demands. In this paper, Part II, existing design provisions for ductile steel plate shear walls are briefly reviewed and discussed, with some modifications recommended, and capacity design provisions for limited-ductility walls are proposed based on the development principles presented in Part I. Capacity design provisions for moderately ductile walls are then rationalized based on the development principles for the other two performance levels. The proposed capacity design methods for the limited-ductility and moderately ductile performance levels are applied to design examples, and the results are discussed in the context of the observed performance of two multistory steel plate shear walls tested under cyclic lateral loading.
