For glued laminated timber bending members, the volume factor CV and beam stability factor CL are not applied simultaneously; thus, the lesser of these factors applies. Depending on where the lumber is cut relative to the center of a log i. Living wood contains a considerable amount of free and bound water. Given that the Euler buckling effect is associated only with axial loads, the CP factor applies to the allowable compressive stress parallel to grain, Fc, as shown in Table 5.
Structural wood panel products primarily include plywood and oriented strand board OSB. For rectangular or non-symmetric columns, CP must be determined for both the weak- and strong-axis bracing conditions. Panels can be ordered in longer lengths for special applications. Column Stability Factor CP Tabulated compression design values in the NDS-S are based on the assumption that a compression member is continuously supported along its length to prevent lateral displacement in both the weak and strong axes.
The most common termites are subterranean termites that nest in the ground and enter wood that is near or in contact with damp soil. Wood is foremost a non-homogeneous, non-isotropic material, and thus exhibits different structural properties, depending on the orientation of stresses relative to the grain of the wood. Beams and stringers are a minimum of 5 inches thick, with the width at least 2 inches greater than the thickness dimension. The inspector should consult a lumber supplier or contractor regarding locally available lumber species and grades. The reduction factors in Table 5.

In ASD, characteristic structural values are multiplied by the reduction factors in Table 5. Most bending members in residential construction are laterally supported on the compression edge by some type of sheathing product. When other loads with different duration characteristics are considered, it is necessary to modify certain tabulated stresses by a load duration factor CD as shown in Table 5.
Column Stability Factor CP Tabulated compression design values in the NDS-S are based on the assumption that a compression member is continuously supported along its length to prevent lateral displacement in both the weak and strong axes. The number of plies typically ranges from three to five.
Therefore, for specific design conditions that differ from the standard basis, design property values should be adjusted. For efficient design, it is important to use the appropriate adjustments for conditions that vary from those used to derive the standard design values.
This structural wood detailing book covers the two most important forces: vertical and lateral forces. The reduction factors are implicit in the allowable values published in the NDS-S for standardized conditions.
Some practical solutions include: the chemical treatment of soil; the installation of physical barriers e.
For homes, an exterior weather barrier e. Species within a group have similar properties and are subject to the same grading rules. Moisture Content Wood properties and dimensions change with moisture content MC. This method of dividing the chapters helps the user to become easily familiar with this reference book.
The most common lumber treatment is CCA copper chromium arsenatewhich should be used for applications such as sill plates located near the ground and for exterior decks. Its loss affects neither volume nor structural properties.
The value is usually the mean average or 5th-percentile test value. The beam stability factor does, however, apply to conditions such as ceiling joists supporting unfinished attic space.
Each sheet contains the drawing itself, a description of the detail, a check list which summarizes the detail, and a small plan view which suggests the location on the structural drawing where the detail can be applied.
Cr, Repetitive Member Factor, applies to bending members in assemblies with multiple members spaced at maximum 24 inches on center. Wood members that are in contact with the ground should be preservative-treated.
Based on the expected application, the tabulated values in the NDS are classified by the species of wood as well as by the nominal size of a member.
For more complicated structural details that call for various types of materials and systems, the inspector might have to account for differential shrinkage by isolating members that will shrink from those that will maintain dimensional stability.
For rectangular or non-symmetric columns, CP must be determined for both the weak- and strong-axis bracing conditions.
For members with no splits, CH equals 2. Cc, Curvature Factor, applies only to curved portions of glued, laminated bending members.Apr 15, · Designed so that professionals can create the structural calculation package and the detailing as quickly and economically as possible.
Contains representative drawings, each one on a separate page that includes a description, a checklist summarizing the detail and a small plan view which suggests the location on the structural drawing where the detail can be applied.
