000019501 520__ $$2eng$$aThe City of Napa in California had chimneys damaged from the 2000 Yountville (M5.0) and 2014 South Napa (M6.0) earthquakes. Presented is an analytical study of chimneys to assess key factors affecting behavior. Ground motions recorded at two locations in Napa were used as input to a simplified nonlinear house-chimney computer model, and the responses interpreted. It was found that the house had significant influence on its associated chimney behavior. For unreinforced chimneys, performance was influenced by the masonry flexural tensile strength, and this factor can be quite variable thus leading to erratic damage patterns. If chimneys were properly steel reinforced according to minimum building code requirements, they should have survived the subject earthquakes mostly unscathed suggesting that quality of construction (or lack thereof) was another key factor. Based on the results, suggestions for the formulation of improved chimney fragility functions are offered that are the subject of ongoing research.
