Wooden I-Joists Exposed to Floods, How Do They Perform?
Engineered wooden I-joists are efficient and effective structural members that are typically used in residential and commercial floor and roof diaphragms. The American Wood Council has established that wooden I-joists should be used in dry-service conditions. However, the effects of submerging wooden I-joists in water for extended periods of times is not well studied and if joists have been exposed to long periods of moisture, as is typical in flood events, they are often replaced. The replacement of the I-joists often leads to considerable expenses and the replacement of the entire structure. A small-scale study was initiated to begin to investigate the effects of submerging wooden I-joists in water for extended periods. Twelve I-joists were tested: two each were tested dry, and submerged for one day, two days, three days, five days, and seven days. The strength and load-deflection behavior of the I-joists were determined during the testing. It was determined, that regardless of the amount of time submerged, the ultimate strength decreased by approximately thirty-five percent and the bending stiffness decreased by approximately thirty percent.
