SANCHEZ TIZAPA, Sulpicio  e  MEBARKI, Ahmed. Metodo semi-empírico para estimar la resistencia lateral en muros de mampostería confinada. Ing. sísm [online]. 2009, n.80, pp.113-127. ISSN 0185-092X.

A semi empiric method to evaluate the ultimate shear of confined masonry walls with the assumption of a failure surface by shear effect in the diagonal wall is presented. For its application, masonry and reinforced concrete properties are required. The model provides results that range within 73% up to 113 % of the experimental strength of 25 walls tested under lateral cyclic and monotonic loads in Mexico and Venezuela, with several ratios H/L by using concrete hollow blocks and solid bricks. The applied vertical stresses are the usual values for buildings up to 5 levels.
