While joist hangers are designed and manufactured to withstand substantial loads, there are scenarios where they can bend or fail:
1. Improper Usage of Joist Hangers
Using joist hangers in applications not recommended by the manufacturer can compromise their structural integrity. For instance, if a joist hanger is utilized with a joist or load that exceeds its specified capacity, bending or failure may occur.
2. Overloading or Uneven Weight Distribution
Exceeding the load-bearing capacity of the joist hanger, either due to excessive loads or uneven weight distribution, can cause bending or failure. Uneven distribution places undue stress on specific points of the hanger, leading to bending where the load is concentrated.
3. Inadequate Installation
Improper installation techniques, such as using the wrong size or type of fasteners, failing to drive nails or screws straight, or insufficiently securing the hanger, can compromise its strength and cause bending or failure.
Properly designed, selected, and installed joist hangers are crucial for providing safe and reliable structural connections. While joist hangers are engineered to handle significant loads, it is essential to consider their load-bearing capacity, follow proper installation techniques, and avoid exceeding their specified limits. By following these guidelines, the risk of bending or failure of joist hangers can be significantly reduced, ensuring structural integrity and safety in wooden construction projects.
