Cold-Formed Steel Steel Sheathed Shear Wall Panel examples
In order to check the accuracy of the proposed models, results from quasi-static non-linear analyses of Steel sheathed Cold-Formed Steel Shear Wall Panel have been carried out using CFSSSWP uniaxialMaterial model implemented into OpenSees version 2.4.6. For this purpose, specimens 1C-b and 3C-a tested by Balh (2010) were selected from the literature and analyzed under similar loading conditions. This set of specimens covers a wide range of variation in physical and mechanical characteristics such as: spacing, number, shear strength, diameter of screw fasteners (sc, nc, Vs, and ds); wall aspect ratio (H/W); frame thickness, chord stud moment of inertia, chord stud cross section area, interior stud moment of inertia, yield and tensile strengths of steel frame (tf, Af, Ife, Ifi, fyf, and fuf); sheathing thickness, yield and tensile strengths of sheathing (type, ts, Fys, and Fus); as well as the anchor bolt diameter of the HoldDown system (dt).
Each SWP was subjected to the Consortium of Universities for Research in Earthquake Engineering (CUREE) loading protocol.
