"' 40 The'Level'Shear Brace(iSB) is a specially designed, prefabricated,engineered- 41- . wood panel that helps structures resist lateral forces such as those created by earthquakes and high winds.The International Residential Code(IRC)and - International Building Code(IBC) require wall bracing for lateral loads in all 3_ -F a structures. The iLevel Shear Brace can help you meet those requirements `Itefficiently and confidently with the following features: i • Suitable for residential, multi-family,and light commercial construction • Narrow panel widths have high allowable loads • Works in tall wall and multistory applications • Field adjustable—can be trimmed and drilled ,4 • 12" braces up to 9'tall and 18"and 24" braces up to 12'tall can be substituted for field-built, prescriptive brace panels Available iLevel® Shear Braces TABLE OF CONTENTS iLevel®Shear Brace Width Height(" Weight Portal Kit Typical (lbs) (Included with Brace) Applications - .- iSB 12x1 12" 78" 90 Yes Available Shear Braces and Kits 2 iSB 12x1.5 12" 851" 95 Yes First story only Shear Brace Applications 3 iSB 12x8 12" 93W 1Q5 Yes Kit and Accessory Descriptions 4 iSB 12x9 12" 105W 115 First or second storylo Engineered-Design General Assumptions 5 iSB 12x10 12" 1171" 125 iSB 12x11 12" 1291/4" 140 First story only Stand-Alone Brace 6-7 iSB 12x12 12" 1411/4" 150 Braces on Raised Floor Kits(RFK) 8 iSB 18x1 18" 78" 130 Yes Allowable Out-of-Plane Lateral Loads 8 iSB 18x1.5 18" 851" 140 Yes First story only Portal Frame 10-11 iSB 18x8 18" 931/4" 150 Yes Stacked Shear Braces 12 iSB 18x9 18" 1051/4" 170 Portal Design and Information 9 iSB 18x10 18" 1171/4" 185 First or second story(?)
