89 Engineered Wood Structural Composite Lumber Connectors GENERAL CONNECTOR INSTALLATION STRONG-DRIVE SCREW INSTALLATION FOR LVL POSITIVE ANGLE NAILING PREVENT ROTATION Correct Nailing Approx. 45 o angle Nail at wrong angle Nail too long Use a 10dx1 nail (Simpson N10 HDG shown) Bend the tab with a hammer. Hammer the nail in at approximately 45 angle. The tab is now correctly installed. No Web Stiffener Installed Hanger side flange supports joist top flange. Hangers provide some joist rotation resistance; however, additional lateral restraint may be required for deep joists. Web Stiffener Required Hanger side flange should be at least 60% of joist depth or potential joist rotation must be addressed. Rotation Resistance If non-skewed hanger side flange is less than 60% of joist depth, attach staggered A34 framing anchors above the hanger. No Web Stiffener Results in Rotation Hanger side flange is below the joist top flange. No web stiffener results in rotation, unless restrained by other means. IUT ITT INSTALLATION (VPA SIMILAR) INSTALLATION: Hex washer head allows for easy driving. Built-in reamer and type 17 tip means no pre-drilling required. See illustrations for SDS positioning on different assemblies. Install with high-torque, low-speed drill (5 amp+). Do not over-drive the SDS screws. DESIGN: Allowable load values are derived from testing based on ASTM D-1761. The Designer shall apply adjustment factors per 2001 NDS. Loads shown are C D 1.0. Increase as allowed per code to a maximum CD 1.33. This document uses Douglas Fir-Larch values (G 0.5), as per the LVL and PSL manufacturers instructions. Loads shown are at 100%. Increase as allowed by code. The designer shall specify the location of all screws (stagger screws on opposite faces). Minimum recommended spacing Wide Face: end distance 4", edge distance 1 ", spacing parallel to grain 4", spacing perpendicular to grain 2". Uniform loads in the table below are based on the capacity of the fasteners to transfer loads between plies. The capacity of the LVL beam may be less and should be checked by a qualified Designer or with the manufacturers literature.

If 7" wide beams are not equally loaded on each side, the plf load from the lesser side should be at least 25% of the opposite side. 2. Quantity and spacing of screws in table are for each screw head side of the assembly as shown in the Assembly figures above. 3. The design professional shall ensure that adequate lateral bracing is provided to prevent displacement of the beam due to the torsion created by the structural members framing into the side of the beam assembly.
