This study validates the use of available tools for nonlinear finite element dynamic analysis (NLFEDA) modeling unbonded post-tensioned reinforced concrete (PT-RC) members under drop weight impact and is first attempt at low-velocity to authors’ knowledge. The was performed in two parts. portion determined appropriate mesh material properties testing setup specimens that were generated by autho...

The ultra-high strength self-compacting concrete, UHSSCC is the new generation type of concrete with a compressive strength higher than 80MPa. The application of this type of concrete on the serviceability state in CFRP strengthened unbonded post-tensioned indeterminate I-beam is monitored and the results are compared theoretically using different standards. For this aim, full scale I-beam of 9...

Post-tensioned (PT) construction incorporating bonded tendons with cementitious grouts has been used for highway bridges. The tendon duct and the encapsulating grout materials provide barrier corrosion protection embedded high-strength steel strand. Although generally in good engineering practice, cases of PT have documented relating to inadequate detailing joints development bleed water. Recen...

In bridges, external post-tension habitually comes as cables placed in ducts for which the residual internal space is (imperfectly) filled with a fluid cement grout. Detecting the problems of injection is not practicable visually from the outside, and no effective auscultation tools were found yet. A recent laboratory experiment established that capacitance probes can be employed, but the main ...
