This thesis presents experiments and numerical analysis of a novel cold-formed steel
framed shear wall sheathed with corrugated steel sheets. The objective of this newly designed
shear wall is to meet the growing demand of mid-rise buildings and the combustibility requirement
in the International Building Code. The strength of the novel shear wall is higher than currently
code certified shear wall in AISI S400-15 so that it could be more favorable for mid-rise building
in areas that are prone to earthquakes and hurricanes. Full-scale monotonic and cyclic tests were
conducted on bearing walls and shear walls under combined lateral and gravity loads. Though the
gravity loads had negative effects on the strength and stiffness of the shear wall due to the buckling
of the chord framing members, it still shows promise to be used in mid-rise buildings. The
objective of numerical analysis is to quantify the seismic performance factors of the newly design
shear wall lateral-force resisting system by using the recommended methodology in FEMA P695.
Two groups of building archetypes, story varied from two to five, were simulated in OpenSees
program. Nonlinear static and dynamic analysis were performed in both horizontal directions of
each building archetype. Finally, the results of the performance evaluation verified the seismic
performance factors(R=Cd=6.5 and fl =3.0) were appropriate for the novel shear wall system.
