Abstract
An important part of the design anchorage strands is the proper use of anchor plates, which is responsible for transfer point load (pre-stressing force) from the steel element to the masonry. The anchor plates are usually designed from steel plates that provide transmission of the pre-stressing force from rod (ropes) to the masonry by concentric pressure. Therefore, their size is designed so that was not exceeded the design strength of concentric pressure masonry under the anchor plate. The thickness of the anchor plates contributes to reduce its deformation during tensioning to a minimum. The aim of this paper is performance laboratory measurements of deformation of prestressed masonry especially in the anchorage zone with using anchor plates with dimensions of 150 x 150 about thickness 10 and 20 mm. Prestressed element is a brick corner with a height of 870 mm and thickness 440 mm (exposed masonry). Subsequently are intended of suitable size parameters anchor plates so that they can be used regardless of the site of their future action.
