It is important not only to account for the 200 500 cover beams, but also for the balcony beams, because you are adding a concentrated load at the cantilever end of the beams. Therefore, the designer should be asked to carefully calculate whether there are any hidden dangers?
From a management point of view alone, it is overloading, because only horizontal live loads are allowed on the design railing, and no vertical live loads.

Anonymous users2024-01-22First of all, it is necessary to determine the bearing capacity of the cantilever beam 200*500, and then judge it according to the position and weight of the column! 4 20 refers to the reinforcement of the cantilever beam or the reinforcement of the column? It is advisable to consult a structurist.

Anonymous users2024-01-21It is only a simple consideration from the perspective of force.
The short-form formula As=M
Cantilevered M = 1 2Fl
The height of the cantilever beam can generally be taken L 8 L 4. >>>More
Ratio of external overhang to pressed wall:
If the beam is located on the roof, then: 1:2 >>>More
The picture looks very regular, but it is done by a layman! Or it was drawn by a student who had not graduated. >>>More
The anchorage length and reinforcement method are detailed in the 101-1 atlas, which describes the cantilever beam, which is clear at a glance!
Summary. Generally, take the span of 1 6 1 8, when the cantilever length is greater than 1500 (unless otherwise specified in the construction unit mm), need to add bent reinforcement. The ratio of the length of the embedded masonry of the pick beam to the length of the pick should be greater than that, and when there is no masonry on the pick beam, the ratio should be greater than 2. >>>More
