Are cuts, notches, and holes bored into I-joists allowed freely?

Are cuts, notches, and holes bored into I-joists allowed freely?

• A. Yes, always
• B. Yes, if specified in the design
• C. No, unless permitted by manufacturer’s recommendations
• D. No, they are prohibited under any circumstances

Answer: (C)

The correct response is based on the importance of adhering to manufacturer specifications and guidelines when it comes to modifying engineered I-joists. I-joists are designed with specific load-bearing capacities and structural integrity in mind. When cuts, notches, or holes are introduced into these components, they can potentially compromise the performance and safety of the joists if not done according to established recommendations. Manufacturers provide detailed guidelines about what modifications are permissible, including the size, location, and type of cuts or holes that can be made. These recommendations are based on extensive engineering research to ensure that any changes do not lead to structural failures or safety hazards. Thus, modifications should only be made if they align with the manufacturer's instructions to maintain structural integrity. Permitting such modifications without adhering to guidelines may lead to serious consequences for both the building's safety and its occupants. Hence, the correct answer emphasizes the importance of following these manufacturer recommendations when it comes to the treatment of I-joists.
