Figure 6.2: A Detail from a Suspended Ceiling System (Rush, 1986) Main runners are the load-bearing parts of the suspended ceiling structural grid which are suspended from floor or roof structure. Cross tees are run between the main runners to provide additional support. Flat or T splines may also be used along with main runners and cross tees. The dimensions of these structural elements are critical for structural stability of the suspended ceiling. For most suspended ceilings, there is an option for supporting integrated fittings (lighting fixtures, air diffusers, etc.) via the 115
suspension system. Fittings supported in this way must be compatible with the ceiling system in terms of size, weight, and edge details. A suspended ceiling plenum is the space between the suspended ceiling and roof or floor structure above. This space normally accommodates a number of services such as HVAC equipment, lighting fixtures, sprinkler systems, etc. The depth of plenum is a critical parameter to consider since it determines the available space for included services and directly affects floor-to-ceiling height. Hangers are metal elements with adjustment clips which are used to connect suspended ceiling structure to the building structure. The spacing of hangers is critical for the structural stability of the system. Wall angles are metal L sections which are used to connect panels to the surrounding walls. Their design should be compatible with the rest of the suspension system. 6.3 Suspended Ceiling Design Process Insights into the suspended ceiling design process were gained through the interviews conducted as a part of the case study. The process is summarized below in order to provide a background for the detailed models presented in the next section. 116
