A simplified method is presented for the analysis of laterally loaded wide-flanged shear wall structures with rigid or flexible joints between web and flange. The flange and web elements may be either of solid or framed construction, the latter being included by replacing the frame panel by an equivalent orthotropic plate in which the shear modulus is chosen to model the racking behaviour of the rigidly-jointed frame. The results obtained are compared both with theoretical values obtained by the finite element and frame methods, and with the results from a series of tests on small-scale plexiglass models. The method gives results which are sufficiently accurate for practical purposes, and enable the degree of shear lag in the flange, the effective width, and the lateral deflection to be estimated rapidly.
