- Abstract
The use of lightweight autoclaved aerated concrete (AAC) block masonry is gaining popularity in earthquake-resistant infilled reinforced concrete (RC) frame buildings due to its various benefits. Therefore, appropriate knowledge of the strength properties of AAC block masonry is necessary for a reasonable evaluation of the seismic behavior of such buildings. In the present study, the uncertainties related to the two most critical parameters that control the resistance capacity of infilled masonry are investigated through laboratory experiments, and the best-fitted probability density functions are recommended. Furthermore, the in-plane seismic performances of typical RC frame buildings infilled with AAC block masonry are evaluated in a probabilistic framework considering the recommended probability density functions showing the ineffectiveness of an assumed normal distribution for this purpose. Although lightweight AAC block masonry slightly increases the seismic risk of the building compared to traditional brick masonry due to its lower strength properties, it can be safely used as an infill material in areas with high seismicity, as it achieves the codeprescribed reliability index.
