ABSTRAKIndonesia area extremely vulnerable to earthquake. earthquakes have caused thousands of casualties,
destruction and damage to thousands of infrastructure, as well as trillions of rupiah of funds for
rehabilitation and reconstruction. Prevention of damage due to ground movement can be done through good
structural design and construction process. one of structural system type that is widely used in Indonesian
building houses were confined masonry system. based on seismicity experience, ductility is a very important
parameter to ensuring the safety of structure. results of this study will be used as an alternative technology
of confine masonry ductility enhancement in structural design process. research methodology was
experimental testing and numerical analysis. experiment testing was lateral cyclic full scale. analyzed
aspects of the test results were: strength, stiffness and ductility.Test specimen were three pieces, namely:
conventional model (K), strengthening horizontal model (H) and strengthening diagonal model (D). From the
results of testing and data analysis known that the performance of strength, stiffness and ductility of H model
is superior to other models.
