Abstract: The top horizontal displacement of frame-shearwall structure, the vertical distributing of shearwall's moment, the vertical distributing of shearwall and frame's shear are influenced by λ through inferring and analyzing theoretically, after λ is introduced as the characteristic value offrame shearwall structure's stiffness.The characteristic optimum value λ js researched and educed in frame shearwall structure. The optimum process is expantiated on by an example of engineering, it offers the references to the optimum design of the similar project.
