How should notches and holes be handled in beams according to general rules?

According to general rules for handling notches and holes in beams, the practice is to avoid cutting them altogether whenever possible. Beams are designed to bear loads, and altering them by cutting notches or holes can significantly compromise their structural integrity. Cutting can lead to reduced strength and an increased risk of failure under load.

In structural engineering, maintaining the beam's load-bearing capacity is critical. Any modification, such as notches or holes, has the potential to create points of weakness, making the beam less stable and more prone to bending or breaking. Therefore, the safest approach is to avoid cutting these structural members in the first place.

In cases where alterations are necessary, alternatives such as using steel plates or other reinforcement methods may be considered to maintain the integrity of the beam, but these methods should be done according to engineering standards and advice. Overall, preserving the beam's original structure is vital for safety and stability in construction.
