Beam Size - Column Relationship

In hollow block systems, the width of the beams is generally larger than the width of the column. Leaving aside the regulation criteria and calculations such as 1.2 times the moment capacity, what are your engineering predictions about whether both dimensions of the beam are larger than the dimensions of the column, and if this situation occurs in beams connected to the column from four directions? For example, suppose 60/40 beams are attached to the 60/35 column from the 4 direction. Thanks.
 
Hello, In the regulation, the width of the beam is limited as the height of the beam + the width of the column face where the beam is stuck. If a 40 cm high beam is to be connected to a 60/35 cm column, the maximum beam widths will be as follows. It can be 35+40 = 75 cm when you pierce the 60 cm face of the column, which is 60+40 = 100 cm and 35 cm.
 
I didn't ask this. Although the regulations and calculation results were met, I was curious about your opinions. I think you meant to say that if the regulations are adhered to, there is no problem. In some articles, it is written that beams that are wider than the column cannot reach their full capacity and therefore damage may occur in the junction areas. Attaching 75/40 beams from all four sides to a 70/35 column makes me hesitate. For example, does this require us to take additional precautions? In order to call a column a strong column, is it enough that the difference between the moment capacities of the beams connected to it is 20%+? Thanks.
 
Beam stirrups should be continued in the column-beam junction area by giving small stirrup details in the overflowing part of the column. Apart from that, if the regulation allows, I don't worry too much, a world application that the regulation does not allow is done in the market.
