b). As the ceiling forms the protective membrane for fire-resistance, the asseRblies and their supporting horizontal swctural members are required to be individuaUy fire protected when tho members support direcdy applied loads from a floor and roof, or more than one floor. The ceyuired fire iesistance shail not be less than that ieyuired for individual protection of inembe�s (two-hour fire-resistance to hold up the twa hour exterior wall). Additionally, all walls supporting the two-hour fitt-resistive (horizontal) assembly will be requiad to be of similar fire-resistive consttuction. De.vls are required and all effected wall and floodceiling assemblies should be individually called out in plan and section. Secdon 704.2.6 c). 1'he above mendoned walls will require a parapet if located less than 20' from the properry line and the roofs are either combusdble constructiun or lus than two- hour construction. Section 709.4.1 /nterior Coun. Note that only new code sectrons are shown if not already mentioned above. 1. The bridge within the main court spans between two buildings which have bcen sepazated by an area sepazation wall. This condition violates the requiroments set focth in Section 504.6.1 that a complete sepazadon is required. However, also stated in that section is that portions of buildings separated by the anea separadon wall may be considered separate buildings. A connection between two adjacent buildi:igs is permitted by the utilization of a pedestrian walkway as outlined in Section 409. Based on this assumption,the following comments apply: a). As a court must be unobstructed to the sky by�iefinition, the pedestrian walkway divides the court into two courts,one on either side of the walkway. b). Opening protection for the pedestrian walkway is required per Table 5-A. An assumed property line must be shown (E-W) for each of the two courts. Secdon 409.3 c). Pedestrian walkways shall be conshucted at a minimum of one-hour fire-rcsistive consuvction, or heavy-timber construction in accordance with Section 605.6 Section 409.2 d). Pedestrian walkways at other than grade shall conform ro the rcquirements of a horizontal exit for the required exit out of the connected dwelling units (r�+pe A) and Gazden Deck per Section 409.7. See "Horizontal Exit"secdon below. 2. 'I'he additional assumed property lines will require the ezterior exit balconies to be re- evaluated for exterior wall and opening protecdon. Note that for fire-resistive consuvction and opening protection requirements, the exterior wall is not the interior wall of the exit balcony,but the wall where the railing(typ) is currendy shown. a
