However, further research to measure the CBLs of the full range of composite wood I-joist geometries, unbraced lengths, and loading conditions is needed before a modified design specification can be recommended.
The split-level design required the cutting of existing trusses and the redesign of columns for longer unbraced lengths.
Further research including a more comprehensive study of different unbraced lengths and loading conditions related to SCL materials should be conducted before specific changes to the wood design equations are proposed.
