Coupled Shear Walls with Step-Changes in Thickness

The distribution of bending moments in coupled shear walls with or without step-changes in thickness due to lateral loads is proved to be invariant. The deflection curve is is obtained directly by numerical integration instead of Hetenyi's method of initial conditions,and agrees well with experimental results. It is interesting to note that for certain coupled walls subjected to either uniform or triangular loading, the maximum horizontal displacement is not increased with the reducing of the wall thickness.
