Abstract:The shear performance of two fullsize (2.4m by 3m) specimens of cold-formed steel framing wall with steel X-strap bracing on both sides was studied by test. The simplified calculation model of the lateral stiffness of walls was put forward to deduce the theoretical calculation formula of the lateral stiffness of walls. Combining with test data and finite element analysis results, the practical calculation formula of the lateral stiffness of walls with steel X-strap bracing on both sides was proposed. And the calculation results of the practical calculation formula agree well with experimental data and finite element results. The calculation model of the maximum shear resistance of the wall was proposed by studying the possible failure modes of the walls under the horizontal force.  Combining with test data and finite element analysis results, the practical calculation formulae of the maximum shear resistance of walls with steel X-strap bracing on both sides were obtained. And the calculation results of the formulae are consistent with test data and finite element analysis results.

Keywords:cold-formed steel framing wall; lateral stiffness; shear resistance; practical calculation formula
