Q5.22: In figure 14, it is shown that the bottom right floor is considered as non rentable area because it cannot be access from the upper half and the left side of the area so we have to provide the floor area and also the access to each floor area, are we correct or is there something we misunderstood? Second question, since the boundaries for the floor member is only the span of the member, this means we can make all floor member in plus(+) shape with no X or is there a boundary for that too?

A: Regarding the first question, all rentable floor area must be accessible from the rest of the floor in question.  In Figure 14 of the Design Guide, the bottom right section of floor meets the requirements for maximum spans but would not be counted as rentable floor area because the adjacent sections of floor have spans that are greater than the maximum allowed, making the bottom right section inaccessible.  Regarding the second question, the beam layout is at the discretion of the teams and may be + shaped or x shaped, as long as the span requirements and other requirements of Section 5.6 of the Official Rules are satisfied.
