"secondary rib" の定義と意味

What is a "secondary rib"?

A secondary rib is an additional support in vaulted ceilings that helps strengthen the structure and add decorative detail. It is smaller than the main ribs and typically runs between them, dividing the ceiling into smaller sections. Secondary ribs provide extra support and can create more intricate patterns in the vault design, contributing to both the strength and visual appeal of the space. They are often found in Gothic architecture, where they enhance the overall complexity of the ceiling's appearance.
