This research is carried out to study the effect of external post-tensioning technique on flexural capacity simply supported composite castellated beam experimentally. In this research, seven beams having same dimensions and material properties were cast tested up failure by applied two concentrated loads at 700 mm from each end. Two strands 12.7 diameter fixed side web strengthening located de...

Unbonded post-tensioned (UPT) flat plate concrete slabs are popular for modern continuous multiple bay floor assemblies due to economic and sustainability benefits (reductions in slab thickness and building selfweight) and structural advantages (decreased deflections over larger spans). Only limited research has been conducted on the performance of UPT flat plate slabs under fire conditions, ye...

The utilization of unbounded external reinforcing bars is one of the strengthening methods used after loading stage and before failure. The method has been used in different forms to strengthen members of reinforced concrete structures. To investigate the effect of utilization of post-tensioned reinforcing bars in this method of strengthening, a number of reinforced concrete beams was tested. S...
