Final answer:
The reinforcing element that prevents an I-joist from buckling is called a flange.The flange is typically made of wood or metal and adds extra strength and support to the I-joist. It helps distribute the load evenly and keeps the web of the I-joist from bending or buckling under pressure.
Step-by-step explanation:
The reinforcing element that is installed on both sides of an I-joist to prevent it from buckling at points of high stress is called a flange.
The flange is typically made of wood or metal and adds extra strength and support to the I-joist. It helps distribute the load evenly and keeps the web of the I-joist from bending or buckling under pressure.
