Abstract

In this research, the behavior of an experimental full-scale beam-column joint was studied, consisting of three reinforced concrete elements, 1 column and 2 beams, joined to a structural steel column at the upper level. The test piece in question was subjected to the action of cyclic loads in one direction only, by means of a pseudo-static test for 5000 s, with the purpose of observing which element of the test piece failed and which was the failure mode. The investigation was based on the use of digital images taken of the specimen during the test, and on the loading and unloading cycles, each photo being analyzed with the CORRELI-Q4 subroutine, in order to visualize the places where cracking occurs in the concrete. The use of the application made it possible to reveal how cracking occurs in reinforced concrete throughout the test. The column of reinforced concrete was the one most affected by the cracking, with cracks just below the reinforced concrete beams.
