Sažetak:
The paper presents the testing results of a small scale model of cantilever concrete columns on a shake table, with varying stirrup spacing. During the test, earthquake accelerations were gradually increased. Displacements and accelerations at the top of the earthquake-like columns, as well as the strains in the concrete, vertical bars and stirrups in characteristic points, were measured during each shake table excitation. It was concluded that the distance between stirrups in the concrete column has a significant effect on the size of the cracking zone in the concrete, as well as on the number, location, spacing and width of cracks. By reducing the distance between the stirrups, columns becomes stiffer. That leads to smaller displacements and slightly larger inertial forces under excitation with low accelerations. Maximum displacements at the top of the column with denser stirrups are slightly smaller and the crack zone and crack width in concrete is therefore significantly reduced.
