How to draw the vertical load of longitudinal secondary beam

The circle represents the load transferred from the floor to the column, which is equivalent to transferring half of the load from the left and right triangles and the upper two trapeziums to the column with P 1 as the center. Because the floor load is a surface load and the column is subjected to a concentrated load, the concentrated load is obtained by multiplying the area of the left and right triangles and the upper two trapeziums by the surface load.

P 1 is correct. The longitudinal beam bears the triangular load adjacent to it in the calculation unit. And then passed to the column.
