Precast, Pretensioned, Post-Tensioned Concrete for Bridge Decks
The problem of concrete bridge deck deterioration on many of our newer as well as older bridges is severe, somewhat perplexing as to cause, and difficult to solve. Furthermore, the cost to highway agencies for their repair, and the cost of delay to the highway user, can be extremely large. The use of precast, prestressed concrete for bridge decks is a con cept of construction or reconstruction...
متن کاملComparing Repaired and Undamaged Specimens Test Results of Post-Tensioned Beam to Column Connections
Since, it is essential to provide homeless people by the earthquake with safe, habitable accommodation repairing medium and slight levels of damage at the connection parts should be undertaken. In order to prove that a repaired connection was sufficiently strong, a precast beam to column post tensioned connection was tested in three phases. In phase one, the middle level damage was observed at ...
متن کاملUnbonded Post Tensioned Concrete in Fire: A Review of Data from Furnace Tests and Real Fires
The fire-safe design of concrete structures which incorporate post-tensioned prestressing tendons has recently been the subject of debate within the structural engineering community, particularly when unbonded post-tensioned (UPT) prestressing tendons are used. Despite several studies aimed at furthering our understanding of the response of UPT concrete structures in fire, many aspects of their...
متن کاملExploratory experimental investigations on post - tensioned structural glass beams
The mechanical response of post-tensioned glass beams is explored in this paper. This is done through bending experiments on post-tensioned glass beam specimens with either mechanically anchored or adhesively bonded steel tendons by which a beneficial pre-stress is inflicted on the glass beams. In addition, reference beams with identical geometry but without tendons are tested. From the results...
متن کاملPerformance of the Modified Precast Beam to Column Connection Placed on a Concrete Corbel
Precast concrete structures in Iran are generally designed as continuous columns with hinged beams, thereby making them simple frames. In this system in site show walls in two directions of buildings guaranteed lateral resisting system. However, in order to obtain a seismic resisting frame, the connection between beam and column should be moment resisting and ductile, allowing the formation of ...
