Flexural behaviour of locally post-tensioned reinforced concrete beams

This study investigates the behaviour of locally post-tensioned reinforced concrete beams. Local post-tensioning is an innovative alternative to existing conventional post-tensioning methods that achieves prestressing of concrete beams using conventional reinforcing steel. Four concrete beams were locally post-tensioned and tested. The theoretical predictions were made based on AS3600-2009. A new theoretical approach is proposed to determine the cracking moment of tested beams, since the current design guide was not applicable to this post-tensioning method.
