Experimental testing of RC slab behavior under long-term load

The results of experimental testing of reinforced concrete rectangular slab under long-term load are given in the paper. Rectangular slab has "point of support" at its edges. Reinforcement is placed in the bottom zone, different in each direction. Slab has been subjected to high long-term load for a year. Afterwards, it was unloaded. Slab displacements at different points have been monitored throughout the year and a half, as well as concrete and reinforcement strains at several measuring points. Slab was kept in a room at constant air temperature and humidity. Slab deflection at several point in time, as well as concrete and reinforcement deformations at several places throughout a year and a half are presented.
