A ABNT NBR 8800 (2008) permite dois critérios para avaliação da força cortante longitudinal resistente última em lajes mistas de aço e concreto: método m-k e método da interação parcial. O método m-k é o método considerado internacionalmente como padrão para o cálculo dessa força cortante longitudinal resistente. Neste método, a resistência das lajes é obtida por regressão linear dos resultados de ensaios realizados com fôrma de uma mesma espessura. O método da interação parcial, por outro lado, surge como alternativa ao método m-k, para melhor explorar o comportamento dúctil dos perfis de fôrma de aço disponíveis no mercado, os projetos de mossas mais bem elaborados e a utilização de vãos maiores. Dentro deste cenário, o objetivo deste trabalho é fazer uma análise comparativa entre estes dois critérios. Para atingir este objetivo, lajes mistas, em escala natural e com diferentes dimensões de vãos e altura total, foram construídas e testadas, na condição de simplesmente apoiadas. A fôrma de aço incorporada utilizada foi o steel-deck MF 50 fabricado pela METFORM. A análise dos resultados revela valores similares da força cortante longitudinal resistente última entre os dois critérios para a fôrma de aço incorporada utilizada.

“…Studies conducted by Veljcovic' [13], Tenhovuori [14], Calixto and Lavall [15], Melo [9] and Souza Neto [16] have demonstrated that in models with shear span relatively short, the influence of the friction at the supports is relevant in the determination of the longitudinal shear resistance, whereas for models with long shear span, that effect is reduced. The friction force, F f , is caused by the vertical reaction at the support and appears concentrated at the interface of the steel sheeting with the concrete, as illustrated in Figure 9.…”

The aim of this work is to evaluate the behavior and strength of composite slabs considering the influence of the friction at the sheeting-concrete interface in the region of the support. Results from tests conducted in the Structural Engineering Department of Federal University of Minas Gerais (UFMG) were used. A Steel Deck 60 system was considered, which consists of a trapezoidal profile with “V” shaped embossments. Deflections, end slips and strains of the steel decks were measured, allowing for the analysis of the behavior of the composite slab system and for the determination of its failure mode. The influence of friction of the region of support in the longitudinal shear resistance was evaluated through the partial shear connection method, which also allowed for establishing criteria and determination of analytical expressions for calculating the ultimate load. Comparative analyses reveal that the influence of the friction of the region of support in the shear-bond resistance is more significant in composite slabs with short shear spans. Design expressions which incorporate friction will also be presented. Their application have demonstrated the efficiency of the method for evaluating the longitudinal shear resistance.
