Abstract

Reinforced concrete framed structures in urban areas are usually infilled with interior and exterior masonry walls. However, the effect of masonry infilled wall is often neglected in the analysis of infilled walls by structural engineers, as it is in current practice. But, experimental studies revealed that hexagonal block infilled walls have favourable effects on strength and stiffness of structures. The objective of this paper is to propose a nonlinear macro model for the lateral load analysis of reinforced concrete frames infilled with hexagonal blocks. The analysis procedure, based on the experimental and analytical studies reported in the literature, accounts for the effect of infilled walls. The results of the analyses were compared to damage and residual cracks observed on the masonry infilled walls. Analytical studies conducted shows that hexagonal block infilled wall could adequately be modeled by single and double diagonal compression struts.
