The analysis and design of and the evaluation of design actions for reinforced concrete ductile shear wall structures

Abstract

A comprehensive review of the state of the art in the design of earthquake resisting ductile structural walls is presented. The material has been compiled from the technical literature, the deliberations within the New Zealand National Society for Earthquake Engineering and research efforts at the University of Canterbury. The paper attempts a classification of structural types and elaborates on the hierarchy in energy dissipation. After a review of available analysis procedures, including modelling assumptions, a detailed description of capacity design procedures for both cantilever and coupled shear wall structures is given. The primary purpose of capacity design is to evaluate the critical design actions which can be used in the proportioning and reinforcing of wall actions which can be used in the proportioning and reinforcing of wall sections. An approach to the estimation of structural deformation is suggested. To satisfy the ductility demands imposed by the largest expected earthquake, detailed design and detailing recommendations are given and the application of some of these is presented in an appendix.

“…Fintel [19] and Naaseh [20] recognized the better seismic performances of wall systems as compared with those of frame systems. Paulay and Williams [21] described the evaluation of the design actions and the analysis and the design of R/C ductile shear walls; Paulay [22] approached the problem of the design of ductile R/C structural walls for earthquake resistance; Wood [15] underlined the good behaviour of Chilean wall buildings during the 3 March 1985 earthquake. Coull and Stafford Smith [13] studied the analysis and the design of tall building structures devoting great part of their work to the seismic behaviour of the shear walls; Paulay and Priestley [9], in their book of 1992, collected all their previous studies regarding the seismic design of R/C buildings with particular reference to shear walls and coupled shear walls; Sezen et al [23] highlighted the good behaviour of Turkish wall buildings during the 17 August 1999 earthquake.…”
