Disadvantages of #honeycomb arrows:
Although many discussions about honeycomb beams have been raised recently, and according to a group of designers, due to its implementation issues, especially the life of the beam and its connection by welding (because as we know, connections play a key and decisive role in They transfer load from one member to another member or members, and in case of its unfavorable implementation, the load capacity or resistance of the structural element will be reduced to a large extent. As a result, the issue of effective monitoring of the implementation of welding operations will be very important in the overall quality of the structure. .) Also, the weakness that exists in the area of the beam due to the reduction of its area is one of the weak points of this beam.

The problem of web crippling also exists in the connection part of the cut section, which is very important. In the areas where there is especially concentrated load or near the supports where shear is an effective factor, the control of crushing should not be given more attention, because in these areas the sections are more critical than other parts. Of course, most of these shortcomings can be solved by the correct and optimal use of reinforcing sheets, and sometimes, in cases where the required cross-section is not obtained due to all measures taken, double honeycomb beams can be used. In a cautious view, the use of honeycomb beams has a lower safety factor than other collision sections. But the widespread use of this type of beams is still common in a large scale of construction works due to the advantages that we briefly mentioned.
