During reconstruction of the vaults of the Lima’s cathedral, in the seventeenth century, masterudbuilders searched for construction systems that were more resistant to seismic activity. The original vaults, dueudto the earthquake of 1609, were extremely damaged. This situation motivated a discussion to analyze theudcauses of damages and the features that would require their reconstruction. It was thought desirable that theudnew construction would be Gothic-ribbed vaults, not as a return to an ancient aesthetic style, but because theudmasons thought this kind of vault could better resist the earthquakes than the existing barrel vaults. Howeverudthe continuing damages and collapses prompted a second discussion, to determine the best way to rebuildudthese vaults. This time the problems of the ribbed vaults were discussed under horizontal loads, possible antiseismicudsolutions were adopted and the possibility of changing the masonry vaults for the nascent curved timberudplank in the colonial lands, especially after the highly structural efficient response proven by the woodenudvaults in some parish churches.
