Scott Johnson, a former consulting structural engineer, discusses fire design principles and the role of structural engineers in creating more efficient buildings. Topics include collaborative efforts between architects and engineers, load capacity in a fire, fire resistance requirements and tests, flammable exit panels, and fire system assembly.
Collaboration between architects and engineers is crucial for ensuring fire design requirements are met and that designs meet necessary fire-resistant standards.
Understanding the International Building Code, fire-resistant construction guidelines, and testing standards allows engineers to make informed decisions and provide value-engineered fire-resistant solutions.

Responsibility for fire design
Responsibility for fire design in structural engineering projects is a collaborative effort between architects and engineers. While architects are generally responsible for life safety and determining the criteria for fire-resistant construction, engineers have the opportunity to demonstrate their value by providing input and expertise. The engineer's role is to ensure that designs meet the necessary fire-resistant standards and to offer potential value engineering solutions. Collaboration between architects and engineers is crucial to ensure that fire design requirements are met.
Understanding Fire Design Criteria
Fire design criteria can be found in the International Building Code (IBC), particularly in Chapter 6 and 7. The construction type determines the fire resistance requirements, which can vary from one hour to multiple hours. It is important for structural engineers to familiarize themselves with the IBC and understand how different construction types impact fire design. Additionally, resources such as UL assemblies and the NDS for wood construction provide specific guidelines for fire-resistant construction. By understanding the criteria and available resources, engineers can make informed decisions to ensure the safety and compliance of their designs.
Value of Fire Engineering for Structural Engineers
Fire engineering presents an opportunity for structural engineers to demonstrate their value and expertise. By understanding fire design principles and taking them into account during the design process, engineers can provide solutions that optimize safety and efficiency. For example, engineers can propose alternative systems or configurations that meet fire resistance requirements while potentially reducing the number of layers or using innovative materials. Collaborating with architects and being knowledgeable about fire code requirements allows engineers to proactively address fire safety concerns and contribute to the successful implementation of fire-resistant construction.
Testing and Evaluation Process
Testing fire-resistant assemblies follows specific standards such as ASTM E119 or UL 263. These tests evaluate the performance of materials and systems under fire conditions. The process typically involves working with accredited labs that conduct the tests and obtaining evaluation reports from organizations like UL or ICC. It is important to consider factors like joint treatment, insulation, and panel gaps to ensure the effectiveness of fire-resistant assemblies. By testing and evaluating different materials and configurations, engineers can provide clients with robust fire-resistant solutions.
This Episode we continue our series of conversations at Luisiana Pacific and this time we get to learn all about fire design. We are talking with Scott Johnson who made the transition from consulting structural engineer to a whole host of tasks and skills at LP. We get to hear all about fire deaign, where exactly the responsibilty falls, and how structural engineers can make better more efficient buildings with even a little understanding in this area. As akways, reach out to us on the email below with any questions at all, If we dont know the answer we will happily pass it along to Scott.
