Abstract
Subject: in this paper, the results of some tests are presented for two variants of strengthened joints of support of reinforced concrete flat slabs onto columns with the arrangement of capitals on the upper surface of the flat slab. Research objectives: the tests were conducted to confirm the rationality and reliability of the design solutions of reinforcement. Materials and methods: the tests were performed by loading selected joints of reinforced concrete building’s frameworks under construction conditions. The joints were strengthened by reinforced concrete capitals or in combination with the steel girdle. Results: the experimental data on the response of joints under study was obtained. The analysis of the stress-strain state of the joints was carried out. Practical advantages and disadvantages of such joints were described.
