Structures carry various types of load during their exploitation. The effects of a longterm load component are significant mainly for the structures in which concrete fulfils its static function. Besides some instant effects; however, there are rheological properties of concrete that manifest themselves under applied forces. Creep, for instance, is time-dependent, and its effects can considerably influence deformation in composite steel and concrete structures. In order to verify some theoretical assumptions in practice, several specimens of composite steel and concrete deck bridges were made, containing encased filler beams. These specimens were subjected to constant long-term loading, and deflections and deformations that occurred in them were monitored and recorded.
