Device with rubber pads for testing stress distribution in prestressed concrete beams

摘要

The stress distribution device in concrete compressed bars consists of a mechanical press (2), with centre pressure. Rubber pads (3) are placed on the side supports (1). Under pressure (4) above the beam (5) is a rubber pad (6). On one side of the beam (5) is a modal hammer (7) and on the other side the beam (5) is placed a motion sensor (8).
