Final answer:
Notching or putting holes in truss members can compromise structural integrity and lead to truss failure. Any modifications should be done in consultation with a structural engineer or according to manufacturer guidelines to avoid compromising the truss's strength.
Step-by-step explanation:
The practice of notching or putting holes in truss members can affect the structural integrity of a building. Trusses are engineered to handle specific loads across their entire length, and altering them by notching or drilling without proper guidance could compromise their strength. For any modifications, such as creating openings for utilities or other installations, consulting with a structural engineer or following the manufacturer's guidelines is essential. Unauthorized alterations can lead to uneven load distribution, causing truss failure and potentially catastrophic consequences.
