Do you need to add columns to the balcony beams?

The beam is a cantilever member, and the end of the beam can not have a support point, otherwise it will become a simply supported beam, the calculation mode has changed, and the direction of bending is reversed. The stressed reinforcement of the pick beam is arranged in the upper part, and only two thin erection ribs are arranged below; And the stressed reinforcement of simply supported beam is arranged in the lower part, and the upper part is only equipped with frame vertical reinforcement. Go back to the upstairs friends, and if you find deformations and cracks, you will add pillars to support them, which is equivalent to tossing it repeatedly.

It's like I want to break a chopstick, first bend it up, the upper part of the chopsticks is broken, and then bend it up hard, toss repeatedly, and don't worry about it falling constantly! 1. Different definitions:

A cantilever beam is a beam that is not supported at both ends, one end is buried or poured on the support, and the other end extends out of the beam. The pick beam refers to the vertical stress point that extends from the main structure and has no support at the end of the main body at one end.

Do you mean that the house is a beam, do you need to add columns?

If there is no deformation or crack in the formal design and construction, there is no need for it.
