Design code review on seismic demand and base detailing criteria: an application to wine tanks in Marlborough

Marlborough is the largest wine-growing region in New Zealand. The seismic events of Lake Grassmere 2013 and Kaikōura 2016 caused severe business disruption to wineries due poor performance wine storage tanks connected non-structural components. damage recorded raised two main discussions concerning NZSEE 2009 guidelines for design liquid tanks. first related appropriateness determination importance level adopt In fact, 1 (IL1) (structures presenting a low degree hazard life other property) was adopted most tanks, therefore, horizontal forces designed were extremely low. Adopting 2 (IL2) (normal structures) would have increased overall demand them therefore limited their structural but potentially cost. second concerns detailing critical connections. current guidelines/standards lack provisions. authors compare guideline with Eurocode 8 (EC8) API 650 through six typical dimensions used Zealand industry. Results show that assigning results similar EC8 650, thereby showing countries approach A further comparative analysis also highlighted connection including hierarchy strength totally missing all three standards/guidelines, which lacks information.
