Abstract	Marchini, Allan Carlos Damasceno. Comparative analysis for the design of structural masonry in concrete blocks by allowable stresses method and limit states method . 2014. 68 P. Monografia de Trabalho de Conclusão de Curso de Bacharelado em Engenharia Civil Universidade Tecnológica Federal do Paraná. Campo Mourão, 2014. Structural masonry in concrete blocks is a consolidated building system in metropolitan areas of Brazil, especially in southwest region, justifying the need for continued studies on the structural behavior of the system. In 2011 the standard design code underwent changes, occurring substitution of the NBR 10837:1989 based on the allowable stresses method by the NBR 15961-1 : 2011 based on the limit states method. This change was necessary due to limit states method is a more modern semi probabilistic method, leading to a rational design. The limit state method enables comparisons of different load combinations for various types of cases by multiple weightings coefficients, making the method more secure and approximating better the parameters for design with the real behavior of the structure. This paper compares the design of walls under normal stresses of buildings with 3, 6, and 9 floors in structural masonry by the both methods. The results show that limit states method, depending on the height of the buildings, leads to required resistances of prisms around 10 20% lower than required resistances obtained by the allowable stresses method.
