Cantilever is a beam anchored at one end. The beam carries a load to support where the magnitude is resisted by the moment and the shear stress. The construction support allows for carrying structures without external reinforcement. Cantilevers can also be built by talking or sheets. This is different from the beam only supported as found in post and system bars. A beam is only supported supported at both ends with the load applied between the supports. What is actually asked with cantilever in the building? Seeing that cantilever head is in contrast to a general structural system where beams are anchored at both ends with a pushing load in the middle. Whether it is built on bridges, towers, buildings, furniture, etc., it is actually the same. If you find a structural element that really stays at one end and is completely free on the one lying down, then it's just a cantilever.
It is a method of construction, called balanced cantilever construction where the cast-in-situ or precast segments are built and post tensioned simultaneously at both ends to reduce construction time. Beside, it counterbalances the hogging moment at the pier.
nice animations
Great video. It provides a really good explanation of how balanced cantilever construction is done, using prestressed concrete.
Thanks very much...
It's actually not his video, it's been ripped off and claimed as his.

I am doing this exact job on the beaver river in pen right now
how you are making last tensıon where at the middle
This was very helpful. I specificaly wanted to know how the segments are post tensioned during cast-in-situ balanced cantilever construction method.
what were those red and orange colour filled inside ducts? cement paste? if yes then why it was not continuous throught the length?
how is it cantilever when no end is free?
