** NOTE TO SPECIFIER ** "Seismic Performance" for projects requiring seismic design. Model building codes and ASCE/SEI 7 establish criteria for buildings subject to earthquake motions. If retaining paragraph, show seismic design criteria on Drawings. Delete if not required.

1. Seismic Performance: Structural glued-laminated timber and connectors shall withstand the effects of earthquake motions determined according to ASCE/SEI 7.

2.3 BEAMS

A. Beam Appearance:

** NOTE TO SPECIFIER ** Stock beams are often supplied with this appearance so they may be exposed to view in the finished structure. Delete if not required.

1. Architectural: Voids greater than 3/4 inch ( 19 mm) are filled, three sides (excluding the top) are planed or sanded, and edges are eased on the bottom face of the member. Refer to Drawings for scheduled locations.

** NOTE TO SPECIFIER ** These beams are used in concealed applications or in other places where appearance is not of primary importance, such as such as commercial buildings, warehouses, and garages.

2. Industrial: Voids are not filled, and only the two wide surfaces are planed. Refer to Drawings for scheduled locations.

** NOTE TO SPECIFIER ** BOISE GLULAM® beam products are manufactured with exterior-grade or wet-use adhesives that comply with all recognized standards. The benefit of the BOISE GLULAM® beams is the flexibility of the product. Our beams are manufactured in a variety of widths and depths with lengths up to 66 feet, with or without camber. A wide array of appearance options and layups make this one of the most versatile engineered wood products available. BOISE GLULAM® beams are available through nationwide distribution.

B. Column Appearance: All four edges shall be eased to match the widths of the Architectural glulams beams and have the same architectural appearance. All sides may be exposed to view.

C. Product: BOISE GLULAM as manufactured by Boise Cascade Company.

1. Manufacturing Standards:

a. APA Mill Number: 1107.

b. APA EWS Trademarked Glulam Under These Standards:

1) ANSI A190.1-2012.

2) CSA O122-06 and CSA O177-06.

** NOTE TO SPECIFIER ** In unbalanced beams, typically known as V4s, the bottom lamination is stronger than all the other laminations. This allows for a more efficient use of timber resources. It is very important to install unbalanced BOISE GLULAM® beams with the top side up. (The word "top" is always printed on the corresponding side.) V4 glulams may be designed and installed in both single and multiple-span applications, and in relatively short cantilevers. Delete if not required.

2. Beam Laminations: V4 - Un-Balanced.

** NOTE TO SPECIFIER ** Balanced glulam beams, or V8s, have the same high-strength laminations on both the top and bottom of the beam, creating a symmetric layup. A V8 glulam can be designed for multiple-span conditions and cantilevers. V8s can also be used for single spans, but V4s are most cost-effective for this type of application. V8 BOISE GLULAM® beams may be special ordered at an additional cost; check with your local distributor for availability. Delete if not required.
