Abstract
The article is dedicated to the investigation of a fracture behavior of combined horizontal joints of wallboards from natural hardening foam concrete and the influence of some factors on the ultimate loads for joints. Two of the most valuable factors that influence the ultimate loads for wallboard joints were allocated while planning the experiment: load eccentricity and indirect reinforcement. The samples consisting of three elements (top wallboard, bottom wallboard and floor slab) were made for the experiment. The typical scheme of destruction for the combined joints of wallboards with and without an indirect reinforcement was identified as a result of testing. The table of comparison of the analysis values of the ultimate loads for combined joints by the existing methods and obtained as a result of the analysis by SP “LIRA” with the received experimental data is shown in the article. Moreover, the diagrams of ultimate load relation with load eccentricity and indirect reinforcement are shown in the paper.
