Abstract The article describes recent cases of tendon ruptures by corrosion and investigations carried out on some bridges in France. Several causes related to HDPE ducts have been identified such as damages during handling, threading tensioning strands, defective connection the duct anchorage, damage construction or operation, low quality material, etc. These rupture exclusively concern inject...

The dapped-end beam is a widely utilized structural component that offers many benefits in real-world applications. However, abrupt changes the geometry result complex stress flows, rendering conventional calculation methods unreliable. estimation of bearing capacity becomes particularly challenging when such elements are designed with prestressed reinforcement. Previous studies have identified...
