摘要

Assessment of the accuracy of the predictive models of ultimate load resistance provisioned in design standards is essential to ensuring a minimum level of safety-in-design is maintained. Failure to apply accurate models may lead to overly conservative and non-economical designs, or structures that are unsafe at their intended ultimate limit state. This paper compares the predictive in-plane shear resistance models specified by the European, Canadian, Australian and U.S. masonry design standards, CSA S304-14 (CSA S304-14: Design of masonry structures. Canadian Standards Association, Mississauga, 2014), AS 3700 (AS3700: Masonry structures, Standards Australia, Sydney, 2018), EN 1996-1-1 (EN1996-1-1: Eurocode 6: design of masonry structures—Part 1–1:general rules for reinforced and unreinforced masonry structures, European Committee for Standardization, Brussels, 2022), and TMS 402/602-22 (TMS 402/602-22 Building code requirements and specification for masonry structures, The Masonry Society, Colorado, 2022) to the shear capacities determined experimentally from 72 full-scale cyclic shear tests on fully bedded, unreinforced clay-brick masonry walls. From these comparisons, the predictive capability of these design provisions has been assessed, and the model uncertainty has been derived in probabilistic terms to facilitate future reliability-based investigations.
