Abstract
This paper describes the numerical modeling using OpenSees of steel sheathed cold-formed steel framed shear wall test specimens under dynamic loading. Two modeling phases were carried out; the first phase comprised non-linear models calibrated using existing reversed cyclic shear wall test data, and the second phase involved more advanced models calibrated using data from dynamic shake table tests of single- and double-storey shear walls as well as other ancillary test programs. The second phase models incorporated the behaviour of the hold-downs, floor framing and blocked bare frame, in addition to the sheathing. The final calibrated models were able to accurately predict the displacement and force response time histories of the single- and double-storey shear wall specimens. These calibrated models will later be relied on for Incremental Dynamic Analyses (IDA) of representative building structures to evaluate seismic design provisions for cold-formed steel framed shear walls to be used in conjunction with the National Building Code of Canada (NBCC).
