Why to study this walls• During 1998 to 2003 non regulation was applied in theconstruction of this kind of wall due to were not consider
shear walls. The application was on 5 story buildings,
however many constructors start to build structures of 12, 14
and 16 stories, just like that, without confinement columns.
• On 2003 the NTE-060 Peruvian Concrete Standard include
recommendations for construction of this kind of walls.
• Stiffness contribution of the perpendicular wall is need inorder to know the inelastic behavior under lateral load withand without perpendicular wall.
• Check the new equipment received by UNI from SATREPS
project.
• Compare stresses levels with test results performed at
Yokohama University

CONCLUSIONS• New equipment was implemented in the structural Lab ofCISMID.
• A program for test Two I walls and One H wall has been
initiated.
• Results of the first the walls provide information to continue
the study of the behavior of low ductility wall.
• Next step is the research of the influence of perpendicularwall on low ductility specimens.
• The results will complement our Japanese counterparts
research and we can discuss in order to learn about theinfluence of the flange to web wall.
