This work describes a study about the design of walls and lintels of structural masonry buildings. The safety verifications and limit states are based on Eurocode 6 [1996], following the global trend of probabilistic based design. Design aspects are discussed within this context and formulas based on ultimate limit state design are presented. In order to ilustrate the performed studies a pilot design of a fifteen floor builiding was developed, where the typical storey, mechanical storey and water reservoir are presented. The formwork project is also presented, with the description of the structural and non structural masonry. Wind effects are based on NBR 6123 [1988] and the design model consists of aligned frames, taking into account the pilot building symmetry. Vertical actions are based on NBR 6120 [1980] and slabs are considered to be in the elastic range. Safety checks and of structural member stability are performed in the design, as well as the reinforcement calculation, when required. In the event where design stresses are higher than the limit stresses in the blocks, but not high enough to indicate reinforcement, a grouting criteria is indicated in order to increase masonry strength. Another part of the present work is the determination of the masonry walls to be grouted and reinforced, as well as the design and detailing of a lintel (i.e., a beam over a window and/or door).
