Distribution rectangle is drawn as follows;→
Measure the linear center to center distance of columns connected with stress lines.
...
For direction1, positive direction width is 0.25*max(positive direction length, negative direction length)
...
For direction1, negative direction width is 0.25*max(positive direction length, negative direction length)
...
...
For direction2, positive direction width is 0.25*max(positive direction length, negative direction length)
...
For direction2, negative direction width is 0.25*max(positive direction length, negative direction length)
Distribution rectangle must be symmetrical.
...
Middle strip reinforcements are generated between columns connected with stresslines.For example, determining the reinforcement length of the middle strip region indicated with white circle is as follows;→
Determine the columns that are associated in parallel to middle strip reinforcement with the two end columns of stress line.
→ C9-C54 columns are associated with C53 column and C10-C56 columns are associated with C55.→
Measure the linear clear distance from end columns of stress line to associated columns
...
Measure the maximum column width parallel to reinforcement of two end columns.
...
Sum the half of maximum width with 0.22*maximum distance
...
Draw lines at calculated distance perpendicular to the reinforcement direction and parallel to stress line.
...
The lines must extend to the column distribution rectangles at both ends.
The middle strip rebars are placed in this region.
