- Abstract
- For the program on the determination of structural properties of low-cost house constructions, the Douglas Fir Plywood Association submitted 75 specimens representing prefabricated plywood building panels of both light3weight stress-skin and commercial design. Wall, partition, floor, and roof specimens were of lightweight stress-skin design. Specimens of commercial type panels (2- by 4-in. studs) were for wall construction only, and furnished a basis of comparison of strength and weight with the light weight constructions. The wall specimens were subjected to compressive, transverse, concentrated, impact, and racking loads; and the wall specimens of commercial type included three different constructions for determining resistance to racking. The partiton specimens were subjected to compressive, transverse, impact, and racking loads; the floor specimens to transverse, concentrated and impact loads; and the roof specimens to transverse and concentrated loads. The floor and roof specimens included two different constructions for determining resistance to transverse loads. Transverse, concentrated, and impact loads were applied to both faces of wall specimens. The loads simulated the loads to which the elements are subjected in actual service. The deflection under load and the sets after the load was removed were measured for uniform increments of load. The results are presented in graphs and tables.
