Some state DOTs require x/box beams without CIP concrete deck to be post-tensioned, as illustrated by the image below. The post-tensioned check box in LEAP Bridge Concrete becomes inactive when X-Beam/Box Beam is selected as the beam type. How do I get this to work? am I missing some steps?
Overloading, corrosion, and material aging deteriorate the structural performance of prestressed concrete (PC) bridges. Strengthening techniques are needed to improve the serviceability and extend the life of these deteriorating bridges gophone login. This study examined a strengthening technique with double-layer prestressed steel wire ropes (PSWRs) to enhance the serviceability.
