<p>Steel sheet shear walls with cold formed edge stiffened burring holes are applied to low- to mid-rise housings in seismically active and typhoon- or hurricane-prone regions. A configuration with burrs on the inside and smooth on the outside enables the construction of omitting the machining of holes for equipments and thinner walls with simplified attachments of finishings. In-plane shear experiments and finite element analyses revealed that the walls allowed shear stress to concentrate in intervals between the burring holes. The walls maintained stable shear load and large deformation behavior, and the deformation areas were limited in the intervals and a large out-of-plane waveform in a sheet was effectively prevented owing to edge stiffened burring ribs. The design methods are developed for evaluating the shear load of the walls at story angle from zero to 1/100, using the idea of decreasing the band width of the inclined tension fields on the intervals with the effects of the thickness.</p>

Good Agreement

Experimental studies showed that vertical cracks appeared along the cold-formed steel or the steel sheet on the adaptive-slit shear walls when the wall was subjected to horizontal earthquake loading, and the adaptive-slit shear wall experienced the loading process from the whole wall section to the slitted wall section. So the appearance and development of the vertical cracks can reflect the seismic behavior of adaptive-slit shear walls. According to the mechanical characteristics of the adaptive-slit shear walls, this paper proposed a method to calculate the cracking load. It is found that the calculated results has a good agreement with the experimental results.

Post Buckling

Steel sheet shear walls are panels in which sheets with burring holes aligned along the vertical direction are fastened to frame members and are applied to multi-story buildings in seismic regions. The wall that receives the in-plane shear force allows shear stress to concentrate in intervals between the burring holes. Finite element analyses and in-plane shear experiments revealed that all intervals between the holes were simultaneously deformed, and buckling areas were limited in the intervals by ring-shaped ribs of the burring holes. The effects of cross-rails are minimal in elastic region. Post-buckling behavior depends on tension fields on the intervals and restraints by cross-rails. The allowable design strength formulas and the indices of strength after buckling are developed.

The objective of this article is to present finite element modelling protocols and validation studies for the new cold-formed-steel-framed shear walls sheathed with steel sheet and gypsum boards. In this model, the nonlinear behaviours of the tapping screw connectors are represented by employing the ‘Pinching4’ material along with ‘zeroLength’ elements. The constitutive relationship parameters of the ‘Pinching4’ material were determined based on experimental data from the self-tapping screw connector shear test performed by the authors. The proposed procedure is implemented to generate the analytical specimens of seven full-scale cold-formed steel shear walls in the OpenSees platform. The load–deformation relationships, hysteresis curves and skeleton curves are compared with the test results performed by the authors. The results show that the finite element models can accurately simulate the shear characteristics of the new cold-formed steel shear walls. Finally, the effects of steel sheet thickness, stud thickness, sheathed material and height-to-width ratio of walls on the shear resistance were investigated.
