A member model of reinforced concrete shear wall with boundary columns and beams was proposed for nonlinear and dynamic frame analysis. The reinforced concrete shear wall was idealized as axial springs for columns and a panel under plane stress states with rigid beams at top and bottom floor levels. Two methods were compared, in which isoparametric element and incompatible rectangular element with four nodes for the panel element were used. The model was verified through the analysis of T-shaped wall tests conducted at Yokohama National University in 1994. The analytical results obtained by the proposed model, such as envelope of loaddisplacement, hysteretic loops, shear and flexural displacement components, showed generally good correlation with the experimental results. Shear deformation was overestimated by isoparametric panel element, whereas incompatible rectangular element, which incorporated flexural deformation by using internal displacements, gave better correlation with the experimental results of flexural yielding walls. For the walls in shear failure, the analytical results were basically same either by isoparametric element or incompatible element.
