Exam 14: Materials for Wood Construction-Ii Engineered Wood Products, Fasteners, and Connectors

What is the approximate moisture content in lumber laminations in glulam members?

Discuss the relative advantages and disadvantages of OSB and plywood panels.

Using sketches, illustrate the following connections in wood frame members: (a)face- nailed connection, (b)end- nailed connection, and (c)toe- nailed connection.

Name at least four engineered wood products.

Square- edged floor sheathing requires an additional panel over it, which is typically a 1/4- in.- thick sanded plywood or hardboard, to make it a two- layer (combination)floor sheathing. Why is (additional)panel overlayment required?

Which type of nail is commonly used for connections between framing members in wood light- frame structures? How do we specify the size of nails?

An OSB panel generally has greater shear strength than a plywood panel of the same size and thickness.

Cross- graining makes a plywood panel

Several different types of nails are used in wood frame construction. They are typically distinguished from each other by the

Nails work best when they are subjected to

Nail plates, used to join members of a truss, are generally used only on one face of the truss.

Of the two structural panels (plywood and OSB), which is more commonly used for wall sheathing, floor sheathing, and roof sheathing and why?

OSB panels are made from paper- thin wood wafers. How, then, are OSB panels (like the plywood panels)stronger in their longer direction as compared to the shorter direction?

Plywood panels should be placed with their longer dimension

The most common use of glulam members is in

What are the top and bottom horizontal parts and the vertical part of an I- section called?

Wood I- joists are made of LVL or solid sawn lumber flanges and webs.

Using sketches and notes, explain the difference between a balanced and an unbalanced glulam beam and the situations in which they are specified.

With the help of an example, explain what type of information is provided in the grade stamp of a typical performance- rated engineered wood panel.

Using a sketch and notes, explain the following terms related to a wood roof truss: (a)top chord, (b)bottom chord, (c)web member, (d)panel point, and (e)nail plate.
