Figure 8-0: Overview of the Performance-Based Design Process, Developing Design Fire Scenarios

8.1 General

Once the performance criteria have been established, the engineer needs to focus on the development and analysis of design alternatives to meet these criteria. The first part of analyzing design alternatives is the consideration of possible fire scenarios, which are then filtered into selected design fire scenarios. Once design fire scenarios are established, then trial designs can be developed (see Chapter 9) and evaluated (see Chapter 10) to determine whether they meet the performance criteria for every design fire scenario. Figure 8-1 illustrates this process.


Figure 8-1: Identifying, Developing, and Evaluating Fire Scenarios

The process of identifying possible fire scenarios and developing them into design fire scenarios consists of the following steps:

  • Consider possible fire scenarios (Section 8.2).

  • Define the design fire scenarios, a subset of the possible fire scenarios (Section 8.4).

  • Quantify the design fire scenarios.

Products & Services
Door Closers
Door Closers close a door after it has been manually opened.
Fire Protection Services
Fire protection services install, maintain and monitor safety equipment such as flame and smoke detectors, sprinkler systems, fire alarms and annunciators.
Flexible Heaters
Flexible heaters are devices that can be molded to the shape of a heated object.
Flammability and Fire Testing Services
Flammability and fire testing services evaluate finished products or components through specialized environmental exposure tests.
High Speed Cameras
High speed cameras are video cameras manufactured with an emphasis on extreme frame rates. This allows for the slow-motion analysis of fleeting details and motion that would not be observable with a standard video camera. These cameras find their most meaningful use in scientific and industrial settings.
