You are designing a 31-story apartment building in a large city. Assume that it will be fully sprinklered. What types of construction are you permitted to use under the International Building Code? What re resistance rating will be required for the separation between the apartment oors and the retail stores on the ground oor , assuming the different occupancy areas must be separated? What classes of nish materials can you use in the exit stairway? In the corridors to those stairways ? Within the individual apartments ? If a Red oak board has a ame-spread rating of 100, can you panel an apartment in Red oak? What Þ re resistance ratings are required for partitions between apartments? Between an exit corridor and an apartment ? What type of Þ re door is required between the apartment and the exit corridor? What is the required re resistance rating for the walls around the elevator shafts? For the purposes of this exercise, when referring to Figure 22.7, assume the highest rating requirement where a range of requirements is provided.
