| Abstract: | This paper studies the load-bearing capacity of various concrete tetrapods under quasistatic loading. The tetrapods were made of plain concrete and synthetic-polymer-fiber-reinforced
concrete. Load tests of the tetrapods were performed. The maximum load-bearing capacity and
the residual-load-bearing capacity of the tetrapods (the load-bearing capacity after the first crack
or at different crack widths) were evaluated. The strength and residual-strength values were backcalculated from the load-bearing capacities, and compared with available data from the literature.
The specimens with and without fibers achieved similar maximum load-bearing capacities, with
cracks occurring at identical locations. However, the differences in residual-load-bearing capacity
were more significant. The synthetic-polymer-fiber-reinforced concrete tetrapods exhibited relatively
high residual-load-bearing capacities, even at higher displacements and crack widths. Two different
calculation-procedures were used for the load-bearing-capacity evaluation. A load-displacement
calculation based on the moment-versus-curvature relation and the plastic-hinge approach was
performed, and additionally proved the applicability of the employed calculation-procedures for the
concrete tetrapod load-bearing-capacity evaluation. |
