Most of Indonesian’s residence consists of masonry wall and just a few of its using confined masonry wall. Lack of knowledge about masonry wall and confined masonry wall cause masonry wall is neglected in structural analysis and just considered as architectural element. The effects are the strength and the stiffness of masonry wall uncounted. In fact that masonry wall gives contribution in strength and stiffness significantly like in confined system. The research uses nonlinear numerical analysis where the formerly eksperiment become the reference from numerical model construction. The model consists of reinforced concrete element and masanry element. Reinfored concrete element was modeled by beam – column which can form plastic hinge in the point, meanwhile masonry wall element was modeled with link. There was two nonlinear analysis was made, nonlinear static pushover analysis with SAP v.15 and cyclic loading analysis with Opensees. The result from pushover analysis in some eksperiment models were comparison load toward deformation curves. In eksperiment model which fulfilled development length requirement, numerical pushover curve was similar to eksperiment pushover curve. In eksperiment model which did not fulfill development length requirement, numerical pushover curve was higher than eksperiment pushover curve. Cyclic load analysis was tried at eksperiment model which fulfilled development length requirement, that was Model C, eksperiment vi from Wijaya (2009). The result from cyclic load analysis with Opensees was hysteretic curve. This curve was almost similar to eksperiment hysteretic analysis.
