Box Column Section Optimization: The Key to Enhancing Bending Resistance

Box column section optimization is crucial for enhancing bending resistance. Reasonably increasing the section height can significantly improve the columns bending section modulus and enhance its bending capacity. However, the height is not necessarily the higher the better; it needs to be determined in conjunction with the building space and the overall structure.

Adjusting the width-to-thickness ratio of the section is also critical. A suitable width-to-thickness ratio can avoid local instability, fully utilize the material properties, and improve bending efficiency.

In addition, setting stiffeners inside the section can constrain the deformation of the column wall, further improve the bending stiffness and stability of the box column, and enable it to better withstand bending moments.
