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).

Numerical Modelling and Calibration of CFS Framed Shear Walls under Dynamic Loading

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 final calibrated models were able to accurately predict the displacement and force response time histories of the single- and double-storey shear wall specimens.
