Abstract
The article describes an experiment devoted to the research of the work of the wall panels’ joints under the action of a vertical compression load. A joint, consisting of three elements: the lower and upper wall panels made of normally cured foam concrete and the slab of reinforced heavy concrete of natural hardening was adopted when planning the experiment. Cases where the load is transferred to a structure with eccentricity, as well as the cases with indirect reinforcement of the support zones of the panels were considered during the experiment. The results of the experiment in the form of graphs of the bearing capacity dependence on the studied factors are described. In addition, the schemes of combined joints destruction were obtained by the results of the experiment. Simultaneously with the experiment, the load-carrying capacity was calculated by the finite element method (PC LIRA 9.4). The article is supplied with a table that represents the results of determining the bearing capacity by the experimental research, by the finite element method as well as existing analytical methods. The analysis of the graphs of load-bearing capacity in comparison with studied factors shows that the load-bearing capacity of the structure decreases with increasing eccentricity of the applied load. The effectiveness of indirect reinforcement of the support zones of the wall panels is manifested only if it is evenly spaced on a height of not more than ¼ of the width of the wall panel.
