Cyclic performance of cold-formed steel stud shear walls.

摘要

This thesis contains a summary of previous cold-formed steel stud shear wall test programs in North America, as well as an overview of the seismic requirements for a number of different design standards, i.e. the NBCC, the UBC and the NEHRP guidelines for seismic design. A theoretical method for the prediction of shear capacity based on the first possible failure mode, which follows the adapted American wood design procedure, is presented and the results from this method are compared with peak loads obtained from existing tests. In addition, a preliminary force modification factor for use in seismic design is suggested for use with the NBCC. Finally, future tests of cold-formed steel stud shear walls are proposed and a corresponding test frame is designed. (Abstract shortened by UMI.)
