Effect of Using Partial Continuounity by External Post-Tension on The Simple Composite Beams as a Strengthening Technique [PDF]
The Egyptian International Journal of Engineering Sciences and Technology, 2016 Composite steel-concrete beams are used widely in bridge and buildingconstruction as the main structural elements in flexure. These structures have adesign life and this may be reduced if loads are increased or environmentaldegradation occurs.
