The wood-frame building with a lightweight truss assembly is likely to carry the largest fuel load due to the predominant use of combustible materials in its construction. Wood, as a fuel source, has a high energy content, which means it can ignite and sustain a fire more easily compared to the materials used in other building types. The lightweight truss assembly often incorporates a significant amount of wood, which contributes to the overall fuel load.

In contrast, the modular steel structure and precast concrete building with steel frame construction utilize materials like steel and concrete that are non-combustible or have a much lower combustibility compared to wood. Additionally, the concrete block structure with a steel roof assembly similarly lacks the inherent fuel load that wood presents, as both concrete and steel are not prone to catching fire or burning in the same way that wood does.

Consequently, the nature of the materials used in the construction of the wood-frame building directly supports its designation as having the largest fuel load, making it more susceptible to fire hazards and quicker fire spread compared to the other building types listed.
