ABSTRACT
Historic and heritage buildings form a significant part of the built environment in many urban areas across Canada. Having a lifetime of more than a hundred years, many of them comprise loadbearing unreinforced masonry (URM) walls. The Canadian earthquake engineering community has been gearing towards adaptation of a consequence–based seismic assessment framework for masonry structures. In this case, determining pertinent acceptance criteria (i.e. dependable estimations of deformation capacity) that ought to be linked to the reference performance objectives (degree of negotiable damage) are of primary interest to structural engineers. This paper provides a general review of the current seismic provision guidelines in ASCE/SEI41-17 and the draft version of the new Eurocode 8-III Chapter 11 (2022). The objective is to build up the background of technical guidelines for the seismic assessment of URM walls that would lay the ground for establishing seismic assessment and retrofit procedures for URM structures across Canada for the future editions of the Canadian seismic codes.
