R403.1.3.5.1

Section R403.1.3.5.1 is titled 'Steel reinforcement' and covers the requirements for seismic design categories D₀, D₁, and D₂ footing and stem wall reinforcement bar specifications. The standards reinforcing bar must comply with, a specific standard bar type requirement where the bar is produced from rail steel, and the minimum yield strength is established. The purpose of this section is to prevent structural failure.

The model shows 3 short sections of epoxy coated reinforcing bars of different sizes commonly referenced in this code. (The bar markings in this model have been enhanced for clarity.)
