ALCOCER M., Sergio; HERNANDEZ B., Hugo  y  SANDOVAL R., Harry. Envolvente de resistencia lateral de piso para estructuras de mampostería confinada. Ing. sísm [online]. 2013, n.89, pp.25-54. ISSN 0185-092X.

This paper presents a procedure for calculating the envelope curve of lateral resistances of confined masonry structures with medium or low height. The idealized envelope curve of lateral resistance was defined by parameters obtained with experimental tests performed in Mexico. The analytical envelope curves of lateral resistance are compared with experimental curves obtained in a model tested under cyclic reversible load and a series of tests on models of masonry in shaking table of the II-UNAM. Results suggest an adequate prediction of the elastic limit, maximum resistance and ultimate state. The procedure includes the calculation of local and global ductility and seismic behavior factor.

Palabras llave : envelope curve; confined masonry; ductility; seismic coefficient; seismic coefficient of performance; fault lateral force; vertical load fails.
