Which consequence resulted from timber bridge supports being consumed by persistent moisture for centuries during the Viking age?

💡 Explanation

Lowered tensile strength capacity of saturated timbers occurred due to long-term creep rupture weakening the structure. The viscous deformation allows propagation of existing fissures, because the timber's inherent resistance to tensile forces diminishes over significant humidity exposure, therefore it cannot withstand anticipated loads, rather than showing improved behaviour.
