The document summarizes testing done on LVL (laminated veneer lumber) materials and structures for use in roof trusses. It includes bending and compression tests of individual LVL members as well as full-scale tests of prototype LVL truss systems. Different configurations of LVL trusses were tested and compared to light steel trusses to evaluate their strength properties. Certificates were issued approving the use of LVL truss designs meeting Indonesia's building codes for construction.
