ABSTRACT

This chapter describes dimensional lumber and engineered wood products used in floor framing. It considers floor framing terminology, systems, and construction practices and explains the use of hold-down anchors and other fastening methods in floor framing systems. The chapter presents steel floor framing materials and construction methods and explores the difference in material and use of solid lumber beams and glued-laminated beams. It describes subfloor and underlayment materials, installation, and fastening and provides the importance and use of moisture barriers in floor framing applications. The chapter also considers timber-frame construction practices used in floor framing. Timber-frame construction uses generally large posts and beams, or timbers, for the horizontal and vertical members of the structural system. Timber-frame buildings are constructed using a combination of post and beam, timber framing and conventional stud framing depending on the requirements of the specific building.
