An approximate hand method is proposed for lateral force analysis of asymmetric wall-frame
structures having constant properties along the height. The coupled torsion-bending
differential equations of equilibrium are decoupled using an orthogonal transformation. The
deformations and stress resultants in the wall and frame assemblies are obtained by linearly
combining the respective coefficients of each of the solved decoupled equations, stresses in
members being obtained by simple force distribution formulae. Non-dimensional coefficients …
