Abstract

Using state of the art information concerning the statistical nature of loads acting on light frame structures, distributions of maximum lifetime roof snow load and maximum lifetime floor live load were developed for use in differential reliability analyses of lumber properties data. The dead load was combined with the live load to obtain the total roof or floor load. Utilizing these total loads, contrasting sets of lumber data were analyzed based on the concept of equal reliability. The sensitivity of the reliability analysis to changing load distributions was studied. Subsequently, load distributions were recommended for use in differential reliability analyses of lumber properties data.
