Enhancement Of Compressive Arch Action In Thick Precast And Post-Tensioned Primary Beam Under A Middle Column Removal Scenario, Manh Ha Tran

CIB Conferences

Previous studies have shown that compressive arch action (CAA) is a key load-resisting mechanism in beam–column sub-assemblages subjected to column removal, while current design practice commonly relies on flexural capacity based on plastic theory. This paper presents a comparative study of CAA and flexural capacity for five two-dimensional precast and post-tensioned concrete beam–column sub-assemblages tested under a middle column removal scenario. Flexural capacity is determined based on plastic theory of fully fixed double-span beams. The results show that the ultimate flexural capacity of prestressed specimens is significantly lower than that of the non-prestressed specimen, despite all specimens being designed to …
