When considering the IBC requirements, an architect can increase the number of options from which to select structural materials for an office…

Comprehensive and Detailed Explanation From Exact Extract:

Limiting the building area within allowable maximums based on occupancy and type increases the

range of acceptable structural materials because larger buildings have stricter fire and structural

requirements.

Increasing occupant capacity (A) increases code stringency.

Increasing efficiency ratio (B) is not an IBC classification.

Omitting 2-hour fire ratings (D) is not permitted and would reduce material options.

Thus, reducing building area allows more flexibility in structural material choices under IBC.
