The tasks of the experimental study included determining the design characteristics of autoclave aerated concrete (AAC) beams with a density of 600 kg / cm3, strength 4 MPa. namely, the width of the crack opening of the bending elements, checking the updated methodology for the effect of shear span to depth ratio [a/h], obtaining new data on the work of bending elements when the load approaches maximum, as well as in the stage of the beyond state, the distribution of deflections along the length of the elements, the distribution relative to the strain of the compression zone, tension zone and deformation of the joint zone of the transverse force and the bending moment and obtained experimental data on the bearing capacity and deformability of the beams for various values of span shear. The measured test data provide a basis for evaluating the accuracy of existing strength-design equations to predict the capacity of such specimens. The study in this paper can provide a reliable experimental basis for further analysis and engineering application of AAC beams in the future.
