The Lifespan of a Building: Evolution and Durability
Abstract: Abstract The structural lifespan of buildings and infrastructure decreases over time due to material degradation, with water penetration being a major contributing factor. Excess moisture weakens construction materials, leading to deterioration and reduced service life. Water absorption plays a critical role in structural degradation, particularly affecting foundations when infiltration occurs below ground level. In bridge structures, water-induced foundation instability can lead to failure, while in roadways, moisture weakens pavement layers, …
