Effects of Roof Pitch and Gypsum Ceilings on the Behavior of Wood Roof Diaphragms

Creator:

Kirkham, William J., Gupta, Rakesh, and Miller, Thomas H.

Abstract:

Ten full-size (3.7×4.9m) plywood roof diaphragms were constructed using metal-plate-connected (MPC) common and hip wood trusses or joists, typical of single-family dwelling (SFD) construction. The specimens included three gable roof slopes of 33, 67, and 100%, a hip roof of 33% slope, and a flat roof, with a horizontal bottom...

Practical Analysis for Horizontal Diaphragm Design of Wood-Frame Single-Family Dwellings

Creator:

Kirkham, William J., Miller, Thomas H., and Gupta, Rakesh

Abstract:

Seismic design of wood-frame single-family dwellings’ (WFSFD) lateral force–resisting systems requires determination of the stiffness of horizontal diaphragms and shearwalls. During design, sizes and locations of shearwall openings are often changed, altering shearwall stiffness and loads and requiring a significant redesign effort. Rigid and tributary area method analyses are examined...

Examination of lateral stiffness and strength of pitched residential roof diaphragms with implications for seismic design.

Creator:

Kirkham, William J.

Abstract:

There are about 80 million single-family dwellings (SFD) in the United States, predominantly of wood-frame construction. Of these, 68% are owner occupied. A home is typically the largest single investment of a family, and is often not covered by earthquake insurance, even where it is available. Of all SFD in...
