Reliability of Wood Connections Designed to ASCE 16
Reliability analyses were performed for nailed and bolted wood connections designed to ASCE 16. The reliability analyses were performed using the European yield model to determine the connection capacity. Using reasonable statistics for the random variables in the yield equations, a reliability index was determined for each of the possible failure modes for both single and double-shear connections. Ditlevsen bounds were then determined for the reliability index of the series system consisting of multiple failure modes. These reliability indices show that designs to the present ASCE 16 do not always exhibit consistent reliability across the range of possible designs. One way to increase consistency for nailed connections is to use the full set of yield equations rather than the simplified set of design equations now present in ASCE 16 for most of the connectors. Other modifications may also be desirable since there are somewhat inconsistent reliablity levels even for those connectors designed to the full set of equations, e.g., bolted connections, but these modifications are beyond the scope of this study.
