This paper presents findings from laboratory tests on reinforced autoclaved aerated concrete (AAC) thin-panel floor diaphragms. Data were generated through targeted AAC material property tests, out-of-plane testing of reinforced AAC panels, and in-plane testing of light-frame AAC floor diaphragm assemblages. A group of six reinforced panels resting on joists was tested to determine a design load for one-way floor systems subjected to gravity loads. Results of 10 floor diaphragm specimens were used to develop a strut-and-
tie model that provides a reasonable lower-bound approximation of the ultimate in-plane capacity of one-way floor systems with AAC sheathing. The testing provided reliable design values and the strut-and-tie model fits well with the experimental test data.
