Rib vs Web Vault represents a fundamental architectural distinction in vaulted ceiling construction techniques, each offering unique structural and aesthetic characteristics in architectural design. Rib vaults, which emerged during the Gothic period, feature a skeletal framework of pronounced stone ribs that intersect at central points, creating a network of supporting elements that carry the vault's weight and distribute forces to vertical supports. These ribs not only serve a structural purpose but also contribute to the dramatic visual effect characteristic of Gothic architecture, with the space between ribs typically filled with lighter stone panels. In contrast, web vaults, also known as shell vaults, consist of continuous curved surfaces without visible supporting ribs, creating a smoother, more uniform appearance. The structural mechanics of web vaults rely on the entire surface working as a cohesive unit to distribute loads, making them particularly efficient in terms of material usage and load distribution. The choice between rib and web vaults often depends on various factors including architectural style, structural requirements, construction methodology, and desired aesthetic impact. Rib vaults traditionally offer greater flexibility in spanning irregular spaces and allow for larger windows due to their concentrated load paths, while web vaults excel in creating clean, modern appearances and can be particularly effective in contemporary designs where minimalist aesthetics are desired. The evolution of construction materials and techniques has influenced the application of these vault types, with modern materials like reinforced concrete enabling more innovative interpretations of both styles. Both vault types continue to be relevant in contemporary architecture, with designers often submitting their innovative vault designs to prestigious competitions such as the A' Design Award, particularly in the Architecture, Building and Structure Design Category, where structural innovation meets aesthetic excellence.

Rib vs Web Vault is a fundamental architectural distinction in vaulted ceiling construction methods, representing two distinct approaches to distributing structural loads and creating overhead spatial enclosures. Rib vaults, which emerged prominently during the Gothic period, feature a skeletal framework of intersecting stone or timber ribs that form the primary load-bearing structure, with lighter materials filling the spaces between these structural members. These ribs concentrate forces along specific paths, transferring weight to supporting columns or walls through a network of clearly articulated structural elements. In contrast, web vaults employ a continuous surface of uniform thickness, distributing loads more evenly across the entire vault surface without visible structural members. The aesthetic and engineering implications of these two systems have profound effects on architectural expression and spatial qualities. Rib vaults allow for greater height and larger window openings due to their efficient load distribution, while web vaults often create smoother, more unified ceiling surfaces that can be advantageous for acoustics and visual continuity. The choice between these systems often depends on factors including desired architectural expression, material availability, construction expertise, and structural requirements. Contemporary interpretations of these historical forms continue to evolve through advanced materials and computational design tools, leading to innovative hybrid solutions that can be evaluated through prestigious platforms such as the A' Design Award's architectural design category, where both traditional and modern vaulting techniques are regularly showcased.
